Pleaseee help me

Answer 1

13

Explanation:

Given the following functions, you want (f+g)(-2).

• f(x) = -3x +4
• g(x) = 7 -x²

At x=-2

The values of these functions are ...

f(-2) = -3(-2) +4 = 10

g(-2) = 7 -(-2)² = 7 -4 = 3

Then their sum is ...

(f +g)(-2) = 10 +3 = 13

Answer 2

`(f + g)( - 2) \\ ( - 3x + 4 + 7 - {x}^(2) )( - 2) \\ ( - 3x + 11 - {x}^(2) )( - 2) \\ - 6x + 22 - 2 {x}^(2)`

answer is -6x + 22 - 2x^2

It can also solve further ...

But I can't do !!
