extreme f(x)=x(85-0.05x)-(600+35x)

extreme points

f (x) = x (85 - 0.05 x) - (600 + 35 x)

Maximum (500, 11900)

Solution steps

f^{'} (x) = - 0.1 x + 50

Find intervals:

Increasing

: - \infty < x < 500,

Decreasing

: 500 < x < \infty

Plug

x = 500

into

x (85 - 0.05 x) - (600 + 35 x) : 11900

Maximum (500, 11900)

f (x) = x 5 - x^{2}

P (x, y) = x^{2} - y^{2} + 6 y - 9

f (x, y) = \frac{x ^{3}}{3} - y^{2} - 5 x + x y - 3

h (x) = - 2 x^{2} - 1, - 4 \leq x \leq 3

x^{3} - 12 x^{2} + 45 x - 4
