2-134.

Each of the curves graphed below is not a function. However, restricting the domain or range can turn a non-function into a function. Sketch a copy of each graph below onto your paper. Then highlight the largest portion of each curve that represents a function. In each case, did you restrict the domain or did you restrict the range? 

  1. In each case, can enough of the domain be restricted to create a function?

  1. In each case, can enough of the range be restricted to create a function?
