question
given $f(x) = -2x + 5$, find $f(-1)$.

answer attempt 1 out of 2

Explanation:

Step1: Substitute \( x = -1 \) into \( f(x) \)

Given \( f(x) = -2x + 5 \), replace \( x \) with \( -1 \), so we get \( f(-1) = -2(-1) + 5 \).

Step2: Calculate the expression

First, calculate \( -2(-1) = 2 \), then add 5: \( 2 + 5 = 7 \).
