Step 1: Show working for fâ (x) & fââ (x).
Step 2: find critical point (Require own research). Tip: CP is at (0,0) and it is a U-Shape.
First derivative test proves the shape of the curve. Second derivative test shows the co-ordinate of the critical point in the graph.
Step 3: Draw a graph based on the equation Y = X4
