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

extreme

Maximum (- 7, - 14), Minimum (- 1, - 2)

Solution steps

f^{'} (x) = \frac{x ^{2} + 8 x + 7}{( x + 4 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 7,

Decreasing

: - 7 < x < - 4,

Decreasing

: - 4 < x < - 1,

Increasing

: - 1 < x < \infty

Plug

x = - 7

into

\frac{x ^{2} - 7}{x + 4} : - 14

Maximum (- 7, - 14)

Plug

x = - 1

into

\frac{x ^{2} - 7}{x + 4} : - 2

Minimum (- 1, - 2)

Maximum (- 7, - 14), Minimum (- 1, - 2)
