Since f(d) and g(d) represent two types of discounts that you will receive off of the price, the composite function is f(g(d)) = 0.8d - 15.
In Mathematics and Geometry, a function composition is an operation (∘) that combines two functions f(x) and g(x), in order to produce a composite function h(x) = (g∘f)(x), such that h(x) = g.
In this exercise, we would determine the corresponding output values for the composite functions by using the substitution method as follows;
f(g(d)) = 0.8d - 15
In this context, we can reasonably infer and logically deduce that the composite function is f(g(d)) = 0.8d - 15.
Complete Question:
You go to a store to buy sneakers f(d) and g(d) represent two types of discounts that you will receive off of the price of the sneakers that you want.
Find f(g(d))
f(d)=d-15
g(d)=0.8d
