Consider the point
that undergoes a series of two transformations: a dilation of scale factor 4 folowed by a
reflection about the horizontal axis.
a. what matrix produces the dilation of scale factor 4? what is the cordinate of the point after the dilation?
b. what matrix produces the reflection about the horizontal axis? what is the cordinate of the point after the
reflection?
c. could we have produced both the dilation and the reflection using a single matrix? if so, what matrix would
both dilate by a scale factor of 4 and produce a reflection about the horizontal axis? show that the matrix you
came up with combines these two matrices
