2.03 evaluating functions hw

1. if $f(x) = 5x + 10$,

4a find $f(4)$.
$f(4) = 30$
5 great job!
4b find $f(-4)$.
$f(-4) = $ enter your next step here

Explanation:

Step1: Substitute x = -4 into f(x)

To find \( f(-4) \), we substitute \( x = -4 \) into the function \( f(x) = 5x + 10 \). So we get \( f(-4) = 5(-4) + 10 \).

Step2: Calculate the expression

First, calculate \( 5(-4) \), which is \( -20 \). Then add 10 to it: \( -20 + 10 = -10 \).

Answer:

\( f(-4) = -10 \)
