Since the function is degree 8, it has exactly 8 zeros. It has a maximum of 8 real zeros. The function will have an x-intercept corresponding to every real zero, so it has a maximum of 8 x-intercepts. A polynomial function of degree n has at most n - 1 turning points, so 8 - 1 = 7 turning points, maximum.
