1 answer

Here are the answers to the questions based on the provided information:

Question 2 A) The x-intercepts of the function \( g(x) = (4x - 1)(x + 2) \) can be found by setting each factor equal to zero:

  • \( 4x - 1 = 0 \rightarrow 4x = 1 \rightarrow x = \frac{1}{4} = 0.25 \)
  • \( x + 2 = 0 \rightarrow x = -2 \)

The x-intercepts are therefore \( (0.25, 0) \) and \( (-2, 0) \).

Responses: (0.25, 0) and (-2, 0)


Question 3 A) Without the graph provided, we cannot determine the exact solutions. Assuming that this is a typical context, I would recommend looking for points where the graph intersects the x-axis. However, I cannot accurately answer this without visual information.


Question 4 A) The minimum of the graph described by \( y = (x + 7)^2 + 3 \) occurs at the vertex, which is at the point \( (-7, 3) \).

Responses: (-7, 3)


Question 5 A) Without the graph, I cannot state which equation has the same zeros as the function graphed. Normally, you would look for the factors of the graph that intersect the x-axis.


Question 6 A) To find the zeros of \( y = 4x^2 + 9x - 9 \), use the quadratic formula \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \). Here, \( a = 4 \), \( b = 9 \), and \( c = -9 \).

  1. Calculate the discriminant: \( b^2 - 4ac = 9^2 - 4(4)(-9) = 81 + 144 = 225 \)
  2. \( x = \frac{-9 \pm \sqrt{225}}{2(4)} = \frac{-9 \pm 15}{8} \)

This results in two solutions:

  • \( x = \frac{-9 + 15}{8} = \frac{6}{8} = \frac{3}{4} \)
  • \( x = \frac{-9 - 15}{8} = \frac{-24}{8} = -3 \)

Responses: \( \frac{3}{4} \) and \( -3 \)


Question 7 A) The key characteristics of the function need to be filled based on provided values.

  • Axis of Symmetry: \( x = 1.5 \)
  • Does this function have a minimum or maximum? Minimum
  • x-Intercepts: \( (0.5, 0) \) and \( (2.5, 0) \)
  • y-Intercept: \( (0, -5) \)

Question 8 A) To solve \( x^2 - 25 = 0 \):

  • Factor: \( (x - 5)(x + 5) = 0 \)
  • Solutions: \( x = \pm 5 \)

Responses: \( \pm 5 \)


Question 9 A) For \( (x - 3)^2 - 81 = 0 \):

  • This can be rearranged to \( (x - 3)^2 = 81 \).
  • Therefore, \( x - 3 = \pm 9 \) gives \( x = 12 \) or \( x = -6 \).

Responses: 12 and -6


Question 10 A) Without the options presented, I cannot match the equations. If given specific equations, I would seek common factors or roots.


Question 11 A) In the equation \( x^2 - 14x + c = 13 \), to make it a perfect square:

  • The term needed is \(\left(\frac{-14}{2}\right)^2 = 49\), thus \( c = 49 \).

Responses: 49


Question 12 A) The steps to complete the square for \( x^2 + 12x - 14 = 0 \) are as follows:

  1. \( x^2 + 12x = 14 \)
  2. Add \( 36 \) to both sides (which is \( \left(\frac{12}{2}\right)^2 \)): \( x^2 + 12x + 36 = 50 \)
  3. We factor to get \( (x + 6)^2 = 50 \)
  4. Take square root and then isolate variable: \( x + 6 = \pm\sqrt{50} \)
  5. Final answers are: \( x = -6 \pm \sqrt{50} \)

Question 13 A) In the quadratic equation provided, we have:

  • \( a = -3 \)
  • \( b = 10 \)
  • \( c = 9 \) (rearranging the equation gives \( +9 \))

Question 14 A) For the equation \( 2x^2 = 20 \):

  • Dividing gives \( x^2 = 10 \).
  • There are two solutions, \( x = \pm\sqrt{10} \).

Responses: Two


Question 15 A) Based on the Zero Product Property:

  • Response: At least one of the factors (3x + 4) or (x - 2) must equal 0 for the entire function to equal 0.

Question 16 A) To factor the quadratic expression \( 2x^2 + 7x + 3 \), we can look for factors of \( 2 \cdot 3 \) (which is 6) that add up to 7. This leads to:

  • \( (2x + 1)(x + 3) \)

Responses: (2x + 1)(x + 3)


Question 17 A) We can check if \( x = 4 \) and \( x = 6 \) are solutions of the equation \( x^2 - 10x + 24 \):

  • Substituting \( x = 4 \): \( 16 - 40 + 24 = 0 \) (Yes)
  • Substituting \( x = 6 \): \( 36 - 60 + 24 = 0 \) (Yes)

Responses: Both \( x=4 \) and \( x=6 \) are solutions.
