Let f(x)=x*2-20 and g(x)=2x find (f+g)(-2)

(f+g)(-2)=

(the x*2 means x squared)

The answer to your question is (f + g) (-2) = -20

Step-by-step explanation:

Data

L(x) = x² - 20

g(x) = 2x

(f+ g)(-2) = ?

Process

1.- Calculate (f + g) (x)

(f + g) (x) = x² - 20 + 2x

- Simplification

(f + g) (x) = x² + 2x - 20

2.- Evaluate (f + g)(x) in -2

(f + g)(-2) = (-2)² + 2(-2) - 20

-Simplification

(f + g)(-2) = 4 - 4 - 20

3.- Result

(f + g) (-2) = -20

what the question so we can you out

the correct answer is x/3+10≥32

hope this !
