Step 1: Find ordered pairs by plugging in values for x. and evaluate the function for y value.

EXAMPLE:         x and  y = x^3\ -6x^2\ +\ 9x        


And so on..


Step 2: Plot the ordered pairs (points) on the graph. and draw a line passing through this points.

Step 3: Find the meeting point of the curve with the x axis

EXAMPLE: From the graph (0, 3) is the required point
