The equation c = 10p + 60 can be used to represent the cost of a family cell phone plan, where c is the cost in dollars, and p is the number of phones on the plan. Which statement about the equation is true? The y-intercept is 60, which is the monthly fee for a plan, regardless of the number of phones.
The slope is 60, and because it costs $60 per phone on the plan.
The slope is 10, and there are 10 phones on the plan.
The y-intercept is 10, meaning that it costs $10 to start a plan.

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.
