The equations are .

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

          (Subtract 7 from each side)

                (Apply additive inverse property: )

                        (Apply additive identity property: )

           (Multiply each side by negative one)

                               (Product of two same signs is positive)

The original function is .

Set original function

                (Add 3 to each side)

                     (Apply additive inverse property: )

                                 (Apply additive identity property: )

Next make at table, fill out the table with values for x > 3 and  x < 3, .

First, draw a co-ordinate plane.

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

Observe the graphs, both graphs have different shapes and

points on and have common point is .

The graphs of  and have in common point is .
