Figure out the area of surrounding border around the circle and the area of the dotted section if the hole circle has a diameter of 9

4400

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer: it is a.,b.,d.

step-by-step explanation:

b. f(x) = –√x + 3this is the correct answer
