The function is $\"f$ .

$\"fraction$ (Apply derivative with respect to x)

$\"f$ (The sum rule)

$\"f$ ( $\"fraction$

$\"\"$

To find the critical point then f\\'(x) = 0

$\"f$

$\"2$

$\"c$

$\"x$ (The critical number)

$\"\"$

Because there are no points for which f\\' does not exist. you can conclude that $\"x$ and $\"x$ are the only critical numbers. The table summarizes the testing of the three intervals determined by two critical numbers.

By applying the First Derivative Test, you can conclude that f has one relative minimum at the point $\"open$ and another at the point $\"open$

$\"\"$

Therefore Relative minimum: $\"open$

Relative maxmum: $\"open$ .
