First find the minimum point of the graph.

Since absolute value function can not be negative, the minimum point of the

graph is where .

The original function is .

Set original function

                    (Distributive property: ab +ac = a(b + c))

  (Multiply each side by negative one)

                  (Product of two same signs is positive)

                           (Zero product property: )

According to subtraction property of equality: if a = b, then a c = b c.

               (Subtract 3 from each side)

                           (Additive invrese property: )

                             (Additive identity property: )

Next make at table, fill out the table with values for .

First, draw a co-ordinate plane.

Locate the points on co-ordinate plane and draw the graph through these points.
