Which statements describe the function f(x)=2x-5/2(x^2-1)? Check all that apply.
f(x) has one real zero because it crosses the x-axis once.
f(x) has two real zeros because it crosses the x-axis twice.
f(x) has real zeros at 1 and –1.
f(x) has a real zero at 2.5.
f(x) has x-intercepts at (1, 0) and (–1, 0).
f(x) crosses the x-axis when x = 1 and x = –1.
f(x) has an x-intercept at (2.5, 0).

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.
