The polynomial function x² - 4x + 8 has A) one stationary point that is at x = 4 B) one stationary point that is at x = -2 C) two stationary points, one at x = 0 and one at x = 4 D) two stationary points, one at x = 2 and one at x = -2 E) one stationary point that is at x = 2

Question

Quizplus · Accepted Answer

The derivative of the polynomial function is 2x - 4. Setting the derivative equal to zero gives the stationary point at x = 2.
