Question

Find the value of f(3) for the function.
f(a) = 7(a + 1) - 5
F(3)=?

Answer 1

F(3)=23

Explanation:

F(3)= 7(3+1)-5

F(3)=7(4)-5

F(3)=28-5

F(3)= 23

you always want to do the problem in the parenthesis first. and you replace a with 3

Answer 2

You just need to exchange the “a” with the number 3 so:

f(3) = 7(3+1) - 5 = 7(4) - 5 = 28 - 5 = 23.

f(3) = 23
