Help me fast, plsss! Marlene made a table to relate the number of T-shirts to the total cost. How can you tell from the table that the relationship is not proportional?

INSERT_TEXT
A
The number of T-shirts increases in intervals of one.

B
The rule of multiplying by 8 works for all but 4 T-shirts.

C
The number of T-shirts increases by a different amount than the total cost does.

D
All of the numbers of T-shirts can be multiplied by the same amount to get the cost.

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.
