< Question 1 of 2 For the function f(x)=x-4x+9x-9, state: a) the maximum number of real zeros that the function can have; b) the maximum number of x-intercepts that the graph of the function can have; and c) the maximum number of turning points that the graph of the function can have. The function f(x) = x-4x+9x-9 has a maximum of The function f(x)=x-4x+9x-9 has a maximum of The function f(x) = x - 4x5 + 9x-9 has a maximum of real zeros. x-intercepts. turning points.
