7-127.

The graph of a transformation of has the

*-axis as a line of symmetry and*

*is tangent to the graph at many places. Find a possible equation.*

Since

Since the -axis is a line of symmetry, the point

Since must be a lower boundary line.

Use this information to determine the amplitude and make a possible sketch.
