# How do you find the critical numbers for #h(p) = (p - 2)/(p^2 + 3)# to determine the maximum and minimum?

##### 1 Answer

The critical points are:

#### Explanation:

The critical points of a function are the points for which its derivative is null.

The denominator is strictly positive for every

To determine whether this point are maximums or minimums we could calculate the second derivative, but as it is easy to see the sign of

1) Around

so

2) Around

so
