please be able to explain and describe the steps on how to solve these problems. I am a little confused on how to begin. Thanks!

2 . For the function f ( ac ) = 23 - 3 202 + 4 find the following :( a ) The coordinates of the two critical points ( the left one is a local maximum and the right one*is a local minimum ) .( b ) The coordinates of the axis intercepts ( there are three of them ! ) .( C ) The coordinates of the point of inflection .( d ) Use all of this information to sketch a rough graph of this function .
