8-46.

The graph of a transformation of *y* = cos(*x*) has the *y*-axis as a line of symmetry and (20, 50) as a point of symmetry. The line *y* = 15 is tangent to the graph at many places. Write a possible equation for this graph. Homework Help ✎

If the *y*-axis is a line of symmetry, then there is no horizontal shift.

Make a sketch of the situation.
