Question

F(x) = 3x + 2
What is f(5)?

Answer 1

17, you just substitute the 5 for the x
The new problem would be f(5)= 3(5)+2
Simplify to f(5)=15+2
Answer f(5)= 17

Answer 2

Hello!

f(x) = 3x + 2

Since you are provided with f(5), we will replace every "x" in the equation with the number 5.

f(5) = 3(5) + 2

f(5) = 15 + 2

f(5) = 17

I hope this helps you! Have a great day!
