Question

F(x)=x−9​; g(x)=3x2
f(x)+g(x)

Answer 1

∵ f(x)＝x－9, g(x)＝3x²
∴ f(x)＋g(x)＝3x²＋x－9

Hope my answer helped u :)

Answer 2

Adding Functions

Answer:

`f(x) +g(x) = 3x^2 +x -9`

Explanation:

Given:

`f(x) = x -9`

`g(x) = 3x^2`

Writing
`f(x) +g(x)`:

`f(x) +g(x) \\ (x -9) +(3x^2) \\ x -9 +3x^2 \\ 3x^2 +x -9`
