If f(x) = 2, what is the value of x? (1 point) Responses -6 -6 1 1 2 2 3

11 answers

The function \( f(x) = 2 \) indicates that the output of the function is constantly 2, regardless of the input \( x \). Therefore, \( f(x) \) does not depend on \( x \) and can equal 2 for any value of \( x \).

This means that there are infinitely many values for \( x \) that satisfy the equation \( f(x) = 2 \).

From the given responses (-6, 1, 2, 3), each of these values can be considered as valid responses, since \( f(x) = 2 \) holds true for any \( x \).

Thus, without any restrictions, the output does not lead to a specific value for \( x \). However, among the provided answers, you can choose any number, including:

  • -6
  • 1
  • 2
  • 3

If you have to select one answer, you could choose any of them, but if you're looking for a response that directly matches \( f(x) \), it would typically be more relevant to simply state that \( f(x) = 2 \) for any \( x \).

what is the answer

The function \( f(x) = 2 \) means that the value of \( f(x) \) is always 2, regardless of what \( x \) is. Therefore, \( x \) can be any number (such as -6, 1, 2, or 3) since they all maintain the equality \( f(x) = 2 \).

If you need to select only one answer from the options provided and every option mentioned is valid, pick any of them. However, if you're looking for a straightforward answer, you can choose:

2

as an answer, since it is one of the options and also satisfies \( f(x) = 2 \).

Jose needs to get his vehicle fixed. The mechanic told him that it would cost him $127 for the part and labor would be at a rate of $35 an hour. The function c(h)=35h+127 represents the total cost for Jose to get his car fixed. What is the y variable measured in for this context?(1 point) Responses Dollars per hour Dollars per hour Dollars Dollars Hours Hours Hours per Dollars

In the context of the function \( c(h) = 35h + 127 \):

  • \( c(h) \) represents the total cost in dollars for fixing the vehicle.
  • \( h \) represents the number of hours of labor.

The \( y \) variable in this function, which is \( c(h) \), is the total cost incurred, measured in Dollars.

Therefore, the correct response is:

Dollars.

A soccer player kicks a ball with an initial velocity of 38 feet every second. The functionf(x)=−16x2+38x can be used to model the time the ball is in the air. What is the meaning of the origin for this situation?(1 point) Responses After 38 seconds, the ball is at a height of 16 feet. After 38 seconds, the ball is at a height of 16 feet. After 16 seconds, the ball is at a height of 38 feet. After 16 seconds, the ball is at a height of 38 feet. At 0 seconds, the ball is at a height of 38 feet. At 0 seconds, the ball is at a height of 38 feet. At 0 seconds, the ball is at a height of 0 feet

The function \( f(x) = -16x^2 + 38x \) models the height of the ball in terms of the time \( x \) in seconds after it has been kicked.

The origin, which is the point \( (0, 0) \), in this context corresponds to:

  • \( x = 0 \): This represents the time when the ball is kicked (0 seconds).
  • \( f(0) \): This represents the height of the ball at that moment.

To find the height at 0 seconds:

\[ f(0) = -16(0)^2 + 38(0) = 0 \]

At 0 seconds, the ball is at a height of \( 0 \) feet, indicating that it is on the ground when it is kicked.

Thus, the correct response is:

At 0 seconds, the ball is at a height of 0 feet.

A tuxedo rental company charges a flat fee of $200 plus a $50 per day fee to rent one of their tuxedos. The function that models the cost to rent a tuxedo is t(d)=50d+200, where d represents the number of days in which the tuxedo is rented and t represents the total cost of the rental. Select all reasonable scales for the vertical axis.(3 points) Responses $1 $1 $5 $5 $25 $25 $50 $50 $100 $100 $400

To determine reasonable scales for the vertical axis in the context of the function \( t(d) = 50d + 200 \), we first need to understand the cost structure based on different values of \( d \), the number of days the tuxedo is rented.

The total cost \( t \) can be calculated for various values of \( d \):

  • For \( d = 0 \) (0 days): \[ t(0) = 50(0) + 200 = 200 \]

  • For \( d = 1 \) (1 day): \[ t(1) = 50(1) + 200 = 250 \]

  • For \( d = 2 \) (2 days): \[ t(2) = 50(2) + 200 = 300 \]

  • For \( d = 3 \) (3 days): \[ t(3) = 50(3) + 200 = 350 \]

  • For \( d = 4 \) (4 days): \[ t(4) = 50(4) + 200 = 400 \]

From this breakdown, we see that the total cost for renting a tuxedo varies based on the number of days rented, and the minimum cost starts at $200 and increases by $50 for each additional day.

Given that the maximum cost with the options you've provided likely falls within a few days of rental, reasonable scales for the vertical axis (cost) would include ranges that can accommodate these costs.

Looking at the increments in total rental costs:

  • $200 (base fee)
  • $250 (1 day)
  • $300 (2 days)
  • $350 (3 days)
  • $400 (4 days)

Considering these increments and the provided responses, the reasonable scales for the vertical axis would be:

  • $1 (too small, but commonly used for scales)
  • $5 (too small, but could be useful for detailed scales)
  • $25 (a reasonable increment for visualization)
  • $50 (a reasonable increment)
  • $100 (covers the lower ranges nicely)
  • $400 (this is the maximum cost calculated)

Thus, the most reasonable scales for your vertical axis would be:

  • $25
  • $50
  • $100
  • $400

So select $25, $50, $100, and $400 as the reasonable scales for the vertical axis.

Samantha is studying the population growth of endangered birds. The growth can be modeled by the equation B(t) =100 +35t2 , where B is the population after t, time in years. Complete the table shown.

To complete the table for the function \( B(t) = 100 + 35t^2 \), you'll need to calculate the population \( B \) for different values of \( t \) (time in years).

Please provide specific values of \( t \) that you'd like to calculate, or if you want a general idea of how the population changes over time, I can demonstrate that using a few example values (e.g., \( t = 0, 1, 2, 3, 4 \)).

For now, I will calculate a few sample values:

  1. For \( t = 0 \): \[ B(0) = 100 + 35(0)^2 = 100 \]

  2. For \( t = 1 \): \[ B(1) = 100 + 35(1)^2 = 100 + 35(1) = 100 + 35 = 135 \]

  3. For \( t = 2 \): \[ B(2) = 100 + 35(2)^2 = 100 + 35(4) = 100 + 140 = 240 \]

  4. For \( t = 3 \): \[ B(3) = 100 + 35(3)^2 = 100 + 35(9) = 100 + 315 = 415 \]

  5. For \( t = 4 \): \[ B(4) = 100 + 35(4)^2 = 100 + 35(16) = 100 + 560 = 660 \]

Here’s a summary table of the population after different years:

| \( t \) (Years) | \( B(t) \) (Population) | |------------------|------------------------| | 0 | 100 | | 1 | 135 | | 2 | 240 | | 3 | 415 | | 4 | 660 |

Feel free to let me know if you have specific values for \( t \) that you want to include or if there's anything else you need!
