Charlie Vega · Answer 1

it is NOT one-to-one

Step-by-step explanation:

A one-to-one function must pass the vertical line test (in order to be a function) and the horizontal line test (in order to be one-to-one).

No even-degree polynomial function will pass the horizontal line test. This function is even degree (2), so is not one-to-one.
