A. Write a function f(x) to represent the price after the 80% markup. <span>b. Write a function g(x) to represent the price after the 25% markdown. </span> <span>c. Use a composition function to find the price of an item after both price adjustments that originally costs the boutique $150. </span> <span>d. Does the order in which the adjustments are applied make a difference? Explain. </span> answers
<span>a) f(x) = 1.8x
b) f(x) = 0.75(1.8x)
c) f(150) = 0.75(1.8(150) = $202.50
d) No, it doesn't matter. The result is the same. </span>
Slope is rise over run. So how far do you rise to get up to 3 from -1. Put that over the run, (once you go up that many how far do you run?) Put that as a fraction and simplify if needed.
Just replace all of the x’s with 5 and solve using order of operations. I will post what I got for my answer in the comments of the answer if you need it.
