extreme y=2x^3-24x^2+90x+8

extreme points

y = 2 x^{3} - 24 x^{2} + 90 x + 8

Maximum (3, 116), Minimum (5, 108)

Solution steps

f^{'} (x) = 6 x^{2} - 48 x + 90

Find intervals:

Increasing

: - \infty < x < 3,

Decreasing

: 3 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = 3

into

2 x^{3} - 24 x^{2} + 90 x + 8 : 116

Maximum (3, 116)

Plug

x = 5

into

2 x^{3} - 24 x^{2} + 90 x + 8 : 108

Minimum (5, 108)

Maximum (3, 116), Minimum (5, 108)

f (x) = x^{\frac{2}{3}} (x - 3)

f (x) = 4 x^{3} - 24 x^{2} + 36 x

f (x, y) = x^{3} + 2 x y - 5 x - y^{2}

x^{3} - 12 x^{2} - 45 x + 8

g (t) = e^{4 t^{3}} x ln (3 t - 1)
