extreme f(x)=-1/7 x^2-2x+7

Solution

extreme points

f (x) = - \frac{1}{7} x^{2} - 2 x + 7

Solution

Maximum (- 7, 14)

Solution steps

f^{'} (x) = - \frac{2 x}{7} - 2

Find intervals:

Increasing

: - \infty < x < - 7,

Decreasing

: - 7 < x < \infty

Plug

x = - 7

into

- \frac{1}{7} x^{2} - 2 x + 7 : 14

Maximum (- 7, 14)

domain of f(x)=-6x^2 domain

f (x) = - 6 x^{2}

domain of (sqrt(x+3))/(x-9)domain

\frac{x + 3}{x - 9}

asymptotes of f(x)= 1/x+2 asymptotes

f (x) = \frac{1}{x} + 2

asymptotes of y= x/(x^2-4)asymptotes

y = \frac{x}{x ^{2} - 4}
