Give an example of two numbers that are reciprocals, or multiplicative inverses.

2/7

Step-by-step explanation: take 2/7 × by 7/2 and the 2's cancel and the 7's cancel and you end up with 1

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
