Question

1. if $f(x) = -4x + 9$ and $f(x) = 1$, what is $x$? (options are presented with circles, but specific option text has some unclear parts due to image quality, but the question is about solving for x in the function equation)

Explanation:

Step1: Set function equal to 1

$1 = -4x + 9$

Step2: Isolate the x-term

$-4x = 1 - 9$

Step3: Simplify the right-hand side

$-4x = -8$

Step4: Solve for x

$x = \frac{-8}{-4}$
