Which of the following is a point on the graph as described by the function

y = (2x + 1)} - 4? (1 point)
• (1,2)
• (-1, -5)
• (-1, -3)
• (0,-2)

1 answer

To determine which point is on the graph of the function \( y = (2x + 1) - 4 \), we can simplify the function first:

\[ y = 2x + 1 - 4 = 2x - 3 \]

Now, we can verify each of the given points by substituting the \( x \) values into the function and checking if the corresponding \( y \) value is obtained.

  1. For the point \( (1, 2) \): \[ y = 2(1) - 3 = 2 - 3 = -1 \quad (\text{Does not match } 2) \]

  2. For the point \( (-1, -5) \): \[ y = 2(-1) - 3 = -2 - 3 = -5 \quad (\text{Matches } -5) \]

  3. For the point \( (-1, -3) \): \[ y = 2(-1) - 3 = -2 - 3 = -5 \quad (\text{Does not match } -3) \]

  4. For the point \( (0, -2) \): \[ y = 2(0) - 3 = 0 - 3 = -3 \quad (\text{Does not match } -2) \]

The only point that satisfies the equation is \( (-1, -5) \).

So the point on the graph is \( \boxed{(-1, -5)} \).
