I really need help with Trig Ratios please!

On a trip, you had to change your money from dollars to british pounds.  you got  560  pounds for  800  dollars.  which is a unit rate that describes the exchange

The function f(x) = 14,600(1.1)* represents the population of a town x years after it was established. what was the original population of the town?

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.
