State the number of possible real zeros and turning points of f(x) = x - 6x + 8x5. Then determine all of the real zeros

State the number of possible real zeros and turning points of f(x) = x² - 6x + 8x5. Then determine all of the real zeros by factoring.7 real zeros and 6 turning points; 0, 2, and 47 real zeros and 6 turning points; 0, –2, and –46 real zeros and 5 turning points; 0, 2, and 46 real zeros and 5 turning points; 0, -2, and —4
