extreme f(x)=-6x^2+84x+1000

extreme points

f (x) = - 6 x^{2} + 84 x + 1000

Maximum (7, 1294)

Solution steps

f^{'} (x) = - 12 x + 84

Find intervals:

Increasing

: - \infty < x < 7,

Decreasing

: 7 < x < \infty

Plug

x = 7

into

- 6 x^{2} + 84 x + 1000 : 1294

Maximum (7, 1294)

f (x) = \frac{4 x}{x ^{2} + 1}, - 3 \leq x \leq 3

f (x) = \frac{4 x}{x ^{2} + 1}, - 3 \leq x \leq 0

f (x) = \frac{4 x + 9}{x ^{2} + 9}

f (x, y) = 2 x y - 1

f (2.4) = 3 - 6 (x - 2) + 9 (y - 4)
