Which of the following will form the composite function g(f(x)) shown below?
g(f(x))=5(x-7)squared-4
a. f(x)=(x-7)square and g(x)=-4
b. f(x)=xsquared-4 and g(x)=x-7
c. f(x)= x-7 and g(x)= 5xsquared-4
d. f(x)= 5x-4 and g(x)= (x-7)squared

They should produce 100 Explorers and 275 Grande Expeditions. To maximize revenue, we want to use all 375 frames. Since the more expensive bike take longer to make, we also want to use all 450 hours so we can make as many of the more expensive bikes as possible with the 375 frame. This helps us create a 2 variable system that can be solved. Let x=Explorers and y=Grande Expeditions x+y=375 2x+3y=45.
