Help me on how to do this

13 quarters ($3.25) and 12 dimes ($1.2) is 25 together ($4.45). Thats the closest I got without going over 25 dimes and quarters. Sorry

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
