Suppose H (x) = V/9-7x. Find two functions f and g such that (fog) (x) = H (x). Neither function can be the identity function. (There may be more than one correct answer.) f (x) = 8 (x) = 0 XA medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made. If x machines are made, then the unit cost is given by the function C(x} : 0'2x2140x+29.063. What is the minimum unit cost? Do not round your answer. Unit cost: 35 X 53
