Question

2. Given the following functions f(x) and g(x), solve (f + g)(5) and select the correct answer below:

f(x) = 8x − 13

g(x) = x − 9

23
27
31
40

Answer 1

The answer is 23.

Explanation:

First you insert 5 into the X place in both equations.

f(5)=8(5) - 13 and g(5)=5 - 9

Then you would solve as you normally would.

F(5)=40 - 13, F(5)=27.

G(5)=-4

Then you add them together because that is what the question is asking when the say (f+g).

Your final answer is 23.
