Which statement best describes the domain and range of f(x) = –(7)x and g(x) = 7x? a)f(x) and g(x) have the same domain and the same range. b)f(x) and g(x) have the same domain but different ranges. c)f(x) and g(x) have different domains but the same range. d)f(x) and g(x) have different domains and different ranges.

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.
