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

Explanation:

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

We have the function \( f(x) = -2x + 5 \). To find \( f(-1) \), we substitute \( x = -1 \) into the function. So we get \( f(-1) = -2\times(-1) + 5 \).

Step2: Calculate the expression

First, calculate \( -2\times(-1) \), which is equal to \( 2 \). Then add \( 5 \) to it: \( 2 + 5 = 7 \).

Answer:

\( 7 \)
