extreme f(x)=(x^2+3)/(x^2-16)

extreme

Maximum (0, - \frac{3}{16})

Solution steps

f^{'} (x) = - \frac{38 x}{( x ^{2} - 16 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 4,

Increasing

: - 4 < x < 0,

Decreasing

: 0 < x < 4,

Decreasing

: 4 < x < \infty

Plug

x = 0

into

\frac{x ^{2} + 3}{x ^{2} - 16} : - \frac{3}{16}

Maximum (0, - \frac{3}{16})
