The length of each side of a square was decreased by 2 inches so the perimeter is now 49 inches. what was the original length of each side of the square

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.

Can someone answer this question for me

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x) − 4?
