extreme f(x)=(2x^{5/2})/5-(2x^{3/2})/3-6

extreme

Maximum (0, - 6), Minimum (1, - \frac{94}{15})

Solution steps

f^{'} (x) = x^{\frac{3}{2}} - x^{\frac{1}{2}}

Find intervals:

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 0

into

\frac{2 x ^{\frac{5}{2}}}{5} - \frac{2 x ^{\frac{3}{2}}}{3} - 6 : - 6

Maximum (0, - 6)

Plug

x = 1

into

\frac{2 x ^{\frac{5}{2}}}{5} - \frac{2 x ^{\frac{3}{2}}}{3} - 6 : - \frac{94}{15}

Minimum (1, - \frac{94}{15})

Maximum (0, - 6), Minimum (1, - \frac{94}{15})
