Question

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

2a find the value of $f(4)$.
$f(4) = $ enter your next step here

Explanation:

Step1: Substitute x = 4 into f(x)

To find \( f(4) \) for the function \( f(x) = 4x + 3 \), we substitute \( x = 4 \) into the function. So we get \( f(4)=4\times4 + 3 \).

Step2: Calculate the result

First, calculate \( 4\times4 = 16 \), then add 3 to it. So \( 16+3 = 19 \).

Answer:

\( f(4)=19 \)
