extreme f(x)=7xsqrt(x-x^2)

extreme

Minimum (0, 0), Maximum (\frac{3}{4}, \frac{21 3}{16}), Minimum (1, 0)

Solution steps

f^{'} (x) = \frac{7 ( - 4 x ^{2} + 3 x )}{2 x - x ^{2}}

Find intervals:

Increasing

: 0 < x < \frac{3}{4},

Decreasing

: \frac{3}{4} < x < 1

Plug

x = 0

into

7 x x - x^{2} : 0

Minimum (0, 0)

Plug

x = \frac{3}{4}

into

7 x x - x^{2} : \frac{21 3}{16}

Maximum (\frac{3}{4}, \frac{21 3}{16})

Plug

x = 1

into

7 x x - x^{2} : 0

Minimum (1, 0)

Minimum (0, 0), Maximum (\frac{3}{4}, \frac{21 3}{16}), Minimum (1, 0)
