Consider the function x) given by the following formula. :52 + 12:1: +35 1) Write the domain of f {in interval notation) ' 2) List the critical numbers of f. _ c) List the intervals on which 1' is increasing and decreasing. If there is more than one interval involved! separate them with commas. For example, you might wrilre "(-inf,10),(20.30)". If there are not any, write "none". f is increasing on: f is decreasing on: d) Where are the relative minima and maxima? Relative maxima occur at I 2 Relative minima occur at a
