extreme f(x)=2x^3+3x^2-36x+46

extreme points

f (x) = 2 x^{3} + 3 x^{2} - 36 x + 46

Maximum (- 3, 127), Minimum (2, 2)

Solution steps

f^{'} (x) = 6 x^{2} + 6 x - 36

Find intervals:

Increasing

: - \infty < x < - 3,

Decreasing

: - 3 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = - 3

into

2 x^{3} + 3 x^{2} - 36 x + 46 : 127

Maximum (- 3, 127)

Plug

x = 2

into

2 x^{3} + 3 x^{2} - 36 x + 46 : 2

Minimum (2, 2)

Maximum (- 3, 127), Minimum (2, 2)
