Question

F(x) = x^2 + 1

g(x) = 5 - x
(f+g)(x) = ?
A. X^2 + x - 4
B. X^2 + x + 4
C. X^2 - x + 6
D. X^2 + x +6

Answer 1

`x^(2) - x + 6`

Explanation:

`(f+g)(x) = (x^(2) + 1) + (5 - x) = x^(2) - x + 6`

`x^(2)` has no common term so it's by itself, and so is - x.

The 1 and 5 will be added to get six.

To get the (f + g), you have to add both equations given.
