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

extreme

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

Solution steps

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

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

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

Plug

x = 5

into

x 5 - x : 0

Minimum (5, 0)

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