Zara is serving fresh pie. she starts by cutting the pie in half and then cuts the half into 4 equal pieces. whta fraction of the whole pie is each piece

Step-by-step explanation:

when she cuts the pie in half, each piece she has is of the total pie, and if she then cuts that in four pieces, each piece now is:

This can be better understood with the attached image, where the pie is first cut in half and then each half is cutted in four, so in total there are 8 pieces of pie, an each one is equivalent to :

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
