extreme 5.11x-xsqrt(x)-2

extreme points

5.11 x - x x - 2

Maximum (\frac{261121}{22500}, 17.76782 \dots)

Solution steps

f^{'} (x) = - 1.5 x + 5.11

Find intervals:

Increasing

: 0 \leq x < \frac{261121}{22500},

Decreasing

: \frac{261121}{22500} < x < \infty

Plug

x = \frac{261121}{22500}

into

5.11 x - x x - 2 : 17.76782 \dots

Maximum (\frac{261121}{22500}, 17.76782 \dots)

f (x) = 2 x + 1 y

f (x) = 2 x^{2} + 8 x + 7

y = x^{4} - \frac{4}{3} x^{3}

6 v + x

f (x) = 15 + 4 x - x^{2} [0.5]
