extreme f(x)=(x+14)(x-7)^2

extreme

Maximum (- 7, 1372), Minimum (7, 0)

Solution steps

f^{'} (x) = 3 (x - 7) (x + 7)

Find intervals:

Increasing

: - \infty < x < - 7,

Decreasing

: - 7 < x < 7,

Increasing

: 7 < x < \infty

Plug

x = - 7

into

(x + 14) (x - 7)^{2} : 1372

Maximum (- 7, 1372)

Plug

x = 7

into

(x + 14) (x - 7)^{2} : 0

Minimum (7, 0)

Maximum (- 7, 1372), Minimum (7, 0)
