Atelephone company charges a fixed monthly rate plus a rate per minute of usage. the company charges $155 for 100 minutes of usage and $245 for 200 minutes of usage. an equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). which of the following best describes the steps to draw the graph of y against x? (1 point)
draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 0.9
draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 1.1
draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 1.1
draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [β1, 1] no, f is continuous on [β1, 1] but not differentiable on (β1, 1). no, f is not continuous on [β1, 1]. yes, f is continuous on [β1, 1] and differentiable on (β1, 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.
