A website is having a sale of 15% off the price, x, of
regular-priced items. For its loyalty club members, the
site is offering an additional 15% off the sale price. An
8% shipping and handling fee is then added to the
discounted price to determine the final cost. The
functions below represent each part of a loyalty
member's purchase
Sales price: S(x) = 0.85%
Loyalty member discount L(S) = 0.85S
Final cost: C(L) = 1.08L
Which is the composite function for the price a loyalty
member would pay based on the original price x?
O C(L(x)) = 2.7800x
O C(L(x)) = 0.9180x
O C(L(x)) = 0.7803x
O C(L(x)) = 0.7225x

Step-by-step explanation:

√z is defined only when z >= 0

Therefore √x - 1 is defined only when (x - 1) >= 0, x >= 1.

The only graph that shows the domain x >= 1 is graph Y.
