Question

question given $f(x) = -x - 4$, solve for $x$ when $f(x) = 6$. answer attempt 1 out of 2

Explanation:

Step1: Substitute f(x) with 6

We know that \( f(x) = -x - 4 \) and \( f(x) = 6 \), so we set up the equation \( 6 = -x - 4 \).

Step2: Solve for x

First, add 4 to both sides of the equation: \( 6 + 4 = -x - 4 + 4 \), which simplifies to \( 10 = -x \). Then, multiply both sides by -1 to get \( x = -10 \).

Answer:

\( -10 \)
