Determine the maximum number of real zeros that the following polynomial function may to find the zeros. f(x)=-3x+6x2-x What is the maximum number of zeros that f(x)=-3x3 + 6x2. -x-2 can have? (Type a whole number.) How many positive real zeros may the function f(x) = -3x3 + 6x2-x-2 have? (Type a whole number. Use a comma to separate answers as needed.) ow many negative real zeros may the function f(x)=-3x3 + 6x2-x-2 have? (Type a whole number. Use a comma to separate answers as needed.)
