extreme y=(x^2+9)/(x^2-64)

Solution

extreme points

y = \frac{x ^{2} + 9}{x ^{2} - 64}

Solution

Maximum (0, - \frac{9}{64})

Solution steps

f^{'} (x) = - \frac{146 x}{( x ^{2} - 64 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 8,

Increasing

: - 8 < x < 0,

Decreasing

: 0 < x < 8,

Decreasing

: 8 < x < \infty

Plug

x = 0

into

\frac{x ^{2} + 9}{x ^{2} - 64} : - \frac{9}{64}

Maximum (0, - \frac{9}{64})
