extreme f(x)=3x^2+2x^3

extreme

Maximum (- 1, 1), Minimum (0, 0)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 0,

Increasing

: 0 < x < \infty

Plug

x = - 1

into

3 x^{2} + 2 x^{3} : 1

Maximum (- 1, 1)

Plug

x = 0

into

3 x^{2} + 2 x^{3} : 0

Minimum (0, 0)

Maximum (- 1, 1), Minimum (0, 0)

What is the extreme f(x)=3x^2+2x^3 ?
The extreme f(x)=3x^2+2x^3 is Maximum(-1,1),Minimum(0,0)
