extreme f(x)=f(x)=-8x^2-144x+6

extreme points

f (x) = f (x) = - 8 x^{2} - 144 x + 6

Maximum (- 9, 654)

Solution steps

f^{'} (x) = - 16 x - 144

Find intervals:

Increasing

: - \infty < x < - 9,

Decreasing

: - 9 < x < \infty

Plug

x = - 9

into

- 8 x^{2} - 144 x + 6 : 654

Maximum (- 9, 654)

f (x) = x^{3} - 3 x [0.3]

f (x) = \frac{4860}{x} + 18 x + 731856

f (x) = 3 x^{2} + 4 x - 6

f (x, y) = (x - 3)^{2} - (y - 1)^{2}

f (x, y) = 7 e^{y} - 3 y e^{x}
