Comparing the two functions on the board.
The graph shows two functions. Both functions make a curve and make a mirror reflection. In comparison to y1, y2 is more narrow, and is located at the bottom of the graph. There is also a vertical shift between both functions. Function y2 starts at [-10, -600} and ends at {8, -390}. Function y1 starts at {-10,400} and ends at {8,300}.
