Question

For each function, what is the output of the given input? For f(x)=-5x-7, find f(-1)

Answer 1

To determine the function output for f(-1), substitute -1 into the equation f(x) = -5x - 7, giving us -2 as the output value.

Step-by-step explanation:

To find the output for the function f(x) = -5x - 7 when the input is -1, you need to substitute -1 for x in the function and then simplify. Here's what that looks like step-by-step:

1. Substitute -1 for x: f(-1) = -5(-1) - 7.
2. Multiply -5 by -1: f(-1) = 5 - 7.
3. Subtract 7 from 5: f(-1) = -2.

The output of the function f(x) when the input is -1 is -2.
