Review Application of Differentiation

FInd the derivative:

f(x) = (-2/3)x³ - (1/2)x² + 9x

• -2x² - x + 9

• -2x² + x + 9

• 2x² - x + 9

• 2x² - x - 9

•  (-1, 2)

•  (-1, -4)

• (-1, 14)

• (-1, 8)

• A minimum at ( 0, -4)

• A maximum at (0, -4)

• A minimum at (0,4)

• A maximum at (0,4)

• Maximum point : (2, -28) and minimum point : (-4, 80)

• Minimum point : (2, 28) and maximum point : (-4, 80)

• Minimum point : (2, -28) and maximum point : (4, 80)

• Minimum point : (2, -28) and maximum point : (-4, 80)

Find the coordinates of the stationary point on the curve...

y = 4x² - 4x + 2

• (¹/₂ , 1)

• (1 , ¹/₂)

• (2, 10)

• (10 , 2)
