4) To remodel a bathroom, a contractor charges $30 per hour plus material costs, which amount to $4650. Therefore, the total cost to remodel the bathroom is given by f(x) = 30x + 4650 where x is
the number of hours the contractor works. Find a formula for f-1(x). What does f-1(x) compute?

Can anyone help??

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
