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

Explanation:

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

We have the function \( f(x) = -x + 1 \). To find \( f(-1) \), we replace \( x \) with \( -1 \) in the function. So we get \( f(-1)=-(-1)+1 \).

Step2: Simplify the expression

First, simplify \( -(-1) \), which is equal to \( 1 \). Then we add \( 1 \) to it: \( 1 + 1 = 2 \).
