2.03 evaluating functions hw

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

4a find $f(4)$.
$f(4) = $ enter your next step here

Explanation:

Step1: Substitute x = 4 into f(x)

To find \( f(4) \) for the function \( f(x) = 5x + 10 \), we substitute \( x = 4 \) into the function. So we replace every \( x \) in the function with 4, which gives us \( f(4)=5\times4 + 10 \).

Step2: Calculate the result

First, calculate the multiplication: \( 5\times4 = 20 \). Then, add 10 to that result: \( 20+ 10=30 \).

Answer:

\( 30 \)
