## Question:

{eq}Let \ f'(x) = \frac {-1(x+3)(x-1)}{(x+4)} {/eq}

Find all intervals for which f is increasing. Label the x-value for all relative extreme.

## Maxima and Minima of a real function:

Among the applications of the derivatives, perhaps one of the most important is to obtain the maximum and minimum values of a function, as well as its monotony intervals. In daily life many times we encounter problems in which we must maximize or minimize some useful data.
