In how many ways can the letters payment be arranged if the letter are taken 5 at a time

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

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.
