Find the common ratio for this geometric sequence.

i believe it is B.

I could be wrong, D is my second choice. but since (left to right) its decreasing, im 89% sure it is B 1/9.

2

step-by-step explanation:

1+1=2

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
