Which expression is equivalent to 4sin2(x) – 8sin2(StartFraction x Over 2 EndFraction)?

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function
