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.
of(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).
