What happens if we graph bothandon the same set of axes, using the x-axis for the input to bothand?

[Suggestion: go towww.desmos.com/calculatorand type{-2 < x < 2},{-2 < x < 2}, andy = x{-2 < x < 2}, and describe the relationship between the three curves.] Then post your own example discussing the difficulty of graph bothandon the same set of axes.

Supposeis a function from the set of real numbers to the same set with. We writeto representand. Is it true that? Why? Is the set {l} infinite? Why?
