extreme f(x)=3xsqrt(5-x)

extreme points

f (x) = 3 x 5 - x

Maximum (\frac{10}{3}, 10 \frac{5}{3}), Minimum (5, 0)

Solution steps

f^{'} (x) = \frac{3 ( - 3 x + 10 )}{2 5 - x}

Find intervals:

Increasing

: - \infty < x < \frac{10}{3},

Decreasing

: \frac{10}{3} < x < 5

Plug

x = \frac{10}{3}

into

3 x 5 - x : 10 \frac{5}{3}

Maximum (\frac{10}{3}, 10 \frac{5}{3})

Plug

x = 5

into

3 x 5 - x : 0

Minimum (5, 0)

Maximum (\frac{10}{3}, 10 \frac{5}{3}), Minimum (5, 0)
