What would the expression (fog)(x) represent?

Answer 1

f(x)=x≥100−25g
g(x)=x(.20)

Answer 2

Those are my f(x) and g(x), and now I need help finding out what (f o g)(x) and (g o f)(x) would be

Answer 3

Answer 4

what is f(x) and g(x)

Answer 5

f(x)=x≥100−25
g(x)=x(.20)

Answer 6

The definition makes no sense. Please copy the problem carefully and show your best efforts at a solution.

Answer 7

f(x) is not correct and also g(x)

Answer 8

The whole problem is - You have a coupon for your favorite clothing store for $25 off any purchase of more than $100. The store is also running a 20%-off sale on its entire inventory. Let x be the original price, f(x) be the price with the $25 coupon applied, and g(x) be the price with the 20% discount applied.

Write an expression for f(x) and g(x).

What would the expression (f o g)(x) represent, and would would (g o f)(x) represent.

Attached is what i mean by (f o g) and (g o f)

Answer 10

g(x)=x-1/5

Answer 11

So my g(x)=x-1/5? what about f(x)?

Answer 12

wait, my f(x) would just be f(x)=x-25, right?

Answer 13

f(x)=25x-100, provided x>4

Answer 14

f(g(x))=f(x-1/5)=25(x-1/5)-100
=25x-5-100=25x-105

Answer 15

g(f(x)=g(25x-100)=(25x-100)-(1/5)
=25x-100-(1/5)=25x-(501/5)
