Question

If f(5)=2 and g(5)=9, what is (f+g)(5)

Answer 1

11

Explanation:

You have an equation
`f(x)` and you set
`x=5`, and the result is 2.

You have another equation
`g(x)` and you set
`x=5`, and the result is 9.

Therefore, if you add both equations, represented by
`(f+g)(x)`, and you set
`x=5`, the result is simply 2 + 9 = 11.
