Nora says that the graph of a circle is a function because she can trace the whole graph without picking
up her pencil. Mia says that a circle graph is not a
function because multiple values of xmap to the same
y-value. Determine if either one is correct, and justify
your answer completely.

2 over 5

step-by-step explanation:

tube or goog would be a great resource to with that question
