Question

Find f(4) for f(x)=4x+3
I know I’m asking a lot of these but I stink at math

Answer 1

the answer is 19

Explanation:

1. You substitute the 4 for the x.

2. Next, your do 4 times 4 to get 16 and add to the 3 to equal 19

3. Finally, f(x)=19

Answer 2

f(4)=4*4+3=16+3=19

What you must do is to plug in 4 as x into the function to get your answer.
