The functions f and g are defined as follows. =fx=−4x2x gx+−2x2 find f−5 and g4. simplify your answers as much as possible.

g(-4)=68

Step-by-step explanation:

Plug x = -3 into f(x) to get

f(x)=4x+2

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

f(-3)=-12+2

f(-3)=-10

Plug x = -4 into g(x) to get

g(x)=4x^2-x

g(-4)=4(-4)^2-(-4)

g(-4)=4(16)-(-4)

g(-4)=64+4

g(-4)=68

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
