Finally, let’s examine a reflection of Harry in the line y = x. Graph this line (y = x) on the grid. Using Harry’s characteristic points and the MIRA, graph Harry’s reflection. Complete the charts below with the characteristic points: Harry, y = H(x) Harry’s reflection in y = x: x y x y Compare the points in the two charts. Describe what happens when we reflect in the line y = x. (This should match what we learned in our earlier study of reflections in the line y = x.) A reflection in the line y = x, shows a graph’s inverse. We will study this in more depth in a future unit. Look at the graph of Harry’s inverse. Is the inverse a function? Explain how you know.
