Determine if the function is one-to-one. A parabola is shown facing up with a vertex of 2.5, -6
Elina [12.6K]

<u>ANSWER</u>

It is not one-to-one function

<u>EXPLANATION</u>

A one-to-one function must pass the horizontal line test.

The graph described in the question looks like the one in the attachment.

A horizontal line drawn in red cuts the graph at more than one point.


Therefore the parabola shown facing up with a vertex (2.5, -6) is not a one-to-one function.
