Question

what is the output value of the given function when the input value is 9?
y = -5x - 2
(9, ?)

Explanation:

Step1: Identify the function and input

The function is \( y = -5x - 2 \) and the input \( x = 9 \).

Step2: Substitute x into the function

Substitute \( x = 9 \) into \( y = -5x - 2 \), we get \( y=-5\times9 - 2 \).

Step3: Calculate the result

First, calculate \( -5\times9=-45 \), then \( -45 - 2=-47 \).

Answer:

-47
