Answer to Question #317678 in Algebra for golden

Question

Provide 2 graphs, one that is a one-to-one function and one that is not a one-to-one function. Justify each classification.

Answer 1

One to one

Not one to one

In the one to one graph, every input, x, produces a different answer, y, while in the second graph that is not one to one, we have two input values x that produce the same answer y. For example, when x=3 and x=-3, we have the same y=9 as the answer, which differs from a one to one function.
