Thomas and Sharyn discuss the order of the transformations of the graph of y = -3|x| compared to the graph of y = |x|. Thomas states that the reflection must be applied first. Sharyn claims that the vertical stretch should be applied first.
a) Sketch the graph of y = -3|x| by
applying the reflection first.
b) Sketch the graph of y = -3|x| by
applying the stretch first.
c) Explain your conclusions. Who is
correct?
