Question

13. Let f(x) = 5x + 10 and g(x) = 2*
a) Find f(2)
b) Find g(2)
c) Find f(2) + g(2)

Answer 1

A) f(2) = 20

B) g(2) = 2

C) f(2) + g(2) = 22

Explanation:

For part A, you change the x to become 2, to have the equation of 5(2)+10. You then solve in order to get 20.

For part B, I'm not exactly sure what the equation is, but you do the same thing for part A. Since there is no x variable then just keep the answer you have. Meaning it is 2

Finally, part C is adding your answers from part A and part B to get the final answer of 22.
