Question

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

Explanation:

Step1: Substitute f(x) with 6

We know that \( f(x) = -x - 1 \) and \( f(x) = 6 \), so we substitute to get the equation \( 6 = -x - 1 \).

Step2: Solve for x

First, add 1 to both sides of the equation: \( 6 + 1 = -x - 1 + 1 \), which simplifies to \( 7 = -x \). Then, multiply both sides by -1 to solve for x: \( x = -7 \).

Answer:

\( -7 \)
