Question

question given $f(x) = -x - 3$, solve for $x$ when $f(x) = -2$. answer attempt 1 out of 2

Explanation:

Step1: Substitute f(x) value

We know \( f(x) = -x - 3 \) and \( f(x) = -2 \), so substitute \( f(x) \) in the function:
\( -2 = -x - 3 \)

Step2: Solve for x

Add 3 to both sides:
\( -2 + 3 = -x - 3 + 3 \)
\( 1 = -x \)
Multiply both sides by -1:
\( x = -1 \)

Answer:

\( -1 \)
