extreme f(x)=-3x^2-6x+8

Solution

extreme points

f (x) = - 3 x^{2} - 6 x + 8

Solution

Maximum (- 1, 11)

Solution steps

f^{'} (x) = - 6 x - 6

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < \infty

Plug

x = - 1

into

- 3 x^{2} - 6 x + 8 : 11

Maximum (- 1, 11)

Popular Examples

domain of f(x)=(sqrt(x-4))/(x-8)domain

f (x) = \frac{x - 4}{x - 8}

inverse of y=2x-x^2 inverse

y = 2 x - x^{2}

domain of-sqrt(25-x^2)domain

- 25 - x^{2}

inverse of (x-1)/(x+1)inverse

\frac{x - 1}{x + 1}

slope of y-5=-3(x-17)slope

y - 5 = - 3 (x - 17)
