extreme y=x^2-2x-1

Solution

extreme points

y = x^{2} - 2 x - 1

Solution

Minimum (1, - 2)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 1

into

x^{2} - 2 x - 1 : - 2

Minimum (1, - 2)

Popular Examples

inverse of f(x)=(2x-1)/(3-x)inverse

f (x) = \frac{2 x - 1}{3 - x}

domain of (x^2+1+x)/(x^2+1)domain

\frac{x ^{2} + 1 + x}{x ^{2} + 1}

midpoint (-7,1),(3,-5)midpoint

(- 7, 1), (3, - 5)

domain of f(x)=(x+3)/(2x^2-x-3)domain

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

asymptotes of f(x)= 3/(x^2-1)asymptotes

f (x) = \frac{3}{x ^{2} - 1}
