extreme f(x)=3xsqrt(4-3x)

extreme points

f (x) = 3 x 4 - 3 x

Maximum (\frac{8}{9}, \frac{16}{3 3}), Minimum (\frac{4}{3}, 0)

Solution steps

f^{'} (x) = \frac{3 ( - 9 x + 8 )}{2 4 - 3 x}

Find intervals:

Increasing

: - \infty < x < \frac{8}{9},

Decreasing

: \frac{8}{9} < x < \frac{4}{3}

Plug

x = \frac{8}{9}

into

3 x 4 - 3 x : \frac{16}{3 3}

Maximum (\frac{8}{9}, \frac{16}{3 3})

Plug

x = \frac{4}{3}

into

3 x 4 - 3 x : 0

Minimum (\frac{4}{3}, 0)

Maximum (\frac{8}{9}, \frac{16}{3 3}), Minimum (\frac{4}{3}, 0)

x^{2} + y^{2} + 4 x + 20

\frac{- x + 5}{x ^{2}}

f (x) = \frac{x}{x + 3}, - 1 \leq x \leq 6

f (x) = 4 x y^{2} + 10 x - 4 y^{4} + 9

f (x) = x^{3} - 6 x^{2} + 9 x + 10
