What common object is being described: The locus of all points in space that are 1.5 inches from a circle whose radius is 3 inches.

1. A circle with radius 8 inches and all points outside the circle

2. A circle with radius 8 inches and all points inside the circle

3. A circle with radius 16 inches and all points outside the circle

4. A circle with radius 16 inches and all points inside the circle

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
