Please help meee, at least answer question C The function C(r) =-2x?+38x + 40 models the sales, in hundreds of
millions of dollars, of compact discs for years since 1990.

Part A: rewrite the function to reveal when cells of compact discs are 0$

Part B: what are the zeros of the function?

Part C: use the context to interpret the zeros

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
