. James bought a new TV. He made an initial payment of $40 to the store, and he will pay $20 each month until the TV is paid off. Which equation represents the
relationship between x, the number of payments James has made, and y, the
total amount that James has paid the store?
-
A: y-40x+20
B: y-20
C: y - 20x-40
D: y-20x+40

What is the ratio of the change in y-values to the change in x-values for this function? a) 1: 13 b) 2: 5 c) 5: 2 d) 13: 1

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.
