Which of the following graphs shows a function which is one-to-one?

Select all correct answers.

Select all that apply:

A. A coordinate plane has a horizontal x-axis and vertical y-axis. A line that rises from left to right crosses the negative x-axis and positive y-axis.

B. Graph of a function A coordinate plane has a horizontal x-axis and a vertical y-axis. A curve rises passing through the x-axis to a maximum in the second quadrant, falls to a minimum on the x-axis, and rises infinitely in the first quadrant after crossing the y-axis.

C. A coordinate plane has a horizontal x-axis and vertical y-axis. A parabola that opens downward has its vertex on the negative y-axis.

D. A coordinate plane has a horizontal x-axis and vertical y-axis. A curve that falls from left to right crosses the positive y-axis and the positive x-axis, and then continues to fall in quadrant 4.
