nurali · Answer

To convert feet to inches, you multiply by 12, since there are 12 inches in each foot. So

f(x) = 12x

To convert yards to feet, you multiply by 3, since there are 3 feet in each yard. So

g(x) = 3x

Then the composite function "plugs" g(x) into f(x):

f(g(x)) = 12g(x) = 12(3x) = 36x

This function first converts yards into feet and then feet into inches...so altogether, f(g(x)) converts yards into inches (which makes sense, because there are 36 inches in a yard).

f(g(3)) = 12(3(3)) = 36(3) = 108 inches in 3 yards
