Question

evaluate the function $f(x) = 5x + 2$ at the given values of the independent variable and simplify
a. $f(-1)$ b. $f(x + 2)$ c. $f(-x)$
a. $f(-1) = -3$ (simplify your answer.)
b. $f(x + 2) = 5x + 12$ (simplify your answer.)
c. $f(-x) = \square$ (simplify your answer.)

Explanation:

Step1: Substitute -x into f(x)

Given \( f(x) = 5x + 2 \), substitute \( x = -x \) into the function. So we get \( f(-x)=5(-x)+2 \).

Step2: Simplify the expression

Simplify \( 5(-x)+2 \), which is \( -5x + 2 \).

Answer:

\( -5x + 2 \)
