extreme f(x)=2x^5-6x^4

extreme points

f (x) = 2 x^{5} - 6 x^{4}

Maximum (0, 0), Minimum (\frac{12}{5}, - \frac{124416}{3125})

Solution steps

f^{'} (x) = 10 x^{4} - 24 x^{3}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \frac{12}{5},

Increasing

: \frac{12}{5} < x < \infty

Plug

x = 0

into

2 x^{5} - 6 x^{4} : 0

Maximum (0, 0)

Plug

x = \frac{12}{5}

into

2 x^{5} - 6 x^{4} : - \frac{124416}{3125}

Minimum (\frac{12}{5}, - \frac{124416}{3125})

Maximum (0, 0), Minimum (\frac{12}{5}, - \frac{124416}{3125})
