please solve and show how to get x and y intercepts,critical points, increasing/decreasing sections, inflection points,concaves and minimim/maximum limits

For each problem, find the: x and y intercepts, x-coordinates of the critical points, the function is increasing and decreasing, x-coordinates of the inflection points, op function is concave up and concave down, and relative minima and maxima. Usin sketch the graph of the function. 1) y= = 3
