2. A group of people plan to go skiing over spring break. The ski rental store will rent a pair of skis for $20 plus $5 each day the skis are out.
a) Write a linear model if C is the total cost of the ski rental and d is the number of days you will use the skis.
b) How much will you pay for ski rental if your trip is 4 days?
How many days can you rent skis for $60?

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.
