Question

solve for input of function given output
question
given $g(x) = -x + 4$, solve for $x$ when $g(x) = 0$.

Explanation:

Step1: Substitute \( g(x) \) with 0

We know \( g(x) = -x + 4 \) and \( g(x) = 0 \), so substitute \( g(x) \) in the function:
\( 0 = -x + 4 \)

Step2: Solve for \( x \)

Add \( x \) to both sides:
\( x = 4 \)

Answer:

\( x = 4 \)
