extreme f(x)=4-7x^2

Solution

extreme points

f (x) = 4 - 7 x^{2}

Solution

Maximum (0, 4)

Solution steps

f^{'} (x) = - 14 x

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

4 - 7 x^{2} : 4

Maximum (0, 4)

Popular Examples

domain of ((x+4))/(x^2-9)domain

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

intercepts of f(x)=y^2=x+9 intercepts

f (x) = y^{2} = x + 9

asymptotes of f(x)=(2x^2-5x+5)/(x-2)asymptotes

f (x) = \frac{2 x ^{2} - 5 x + 5}{x - 2}

range of y= 1/(x-3)+2 range

y = \frac{1}{x - 3} + 2

domain of y=(2x+3)/(x(x+1))domain

y = \frac{2 x + 3}{x ( x + 1 )}
