Which of the relations below is not a function? mark that apply.

a) {(-1, -1), (7, 7), (3, 3), (4, 4)}
b) {(6, 3), (6, 4), (6, 9), (6, 12)}
c) {(3, 6), (4, 6), (9, 6), (12, 6)}
d) {(2, -2), (-2, 2) (3, 1), (1, -3)}
e) {(0, 5), (0, 2), (4, 2)}

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

When y’all answer can y’all explain too !

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.
