2.03 evaluating functions hw

1. if $f(x) = 2x - 8$,

5a find $f(5)$
$f(5) = $ enter your next step here

Explanation:

Step1: Substitute \( x = 5 \) into \( f(x) \)

To find \( f(5) \), we substitute \( x = 5 \) into the function \( f(x) = 2x - 8 \). So we get \( f(5)=2\times5 - 8 \).

Step2: Calculate the result

First, calculate \( 2\times5 = 10 \), then subtract 8 from 10: \( 10 - 8 = 2 \).

Answer:

\( f(5)=2 \)
