Question

1. consider the function $f(x) = 4x + 3$.

2a find the value of $f(4)$.
$f(4) = 19$
5 nice work!
2b find the value of $f(8)$.
$f(8) = $ enter your next step here

Explanation:

Step1: Substitute x = 8 into f(x)

To find \( f(8) \), we substitute \( x = 8 \) into the function \( f(x) = 4x + 3 \). So we get \( f(8)=4\times8 + 3 \).

Step2: Calculate the result

First, calculate \( 4\times8 = 32 \), then add 3 to it: \( 32+3 = 35 \).

Answer:

\( f(8)=35 \)
