A coordinate plane is shown. There are five points on the graph at left parenthesis negative 2 comma 2 right parenthesis, left parenthesis negative 1 comma 1 right parenthesis, left parenthesis negative 1 comma negative 1 right parenthesis, left parenthesis 1 comma 1 right parenthesis, and left parenthesis 2 comma 2 right parenthesis.The y-axis goes from negative 5 to 5. The x-axis also goes from negative 5 to 5. The first point is graphed at left-parenthesis negative 2 comma 2 right-parenthesis, the second point is graphed at left-parenthesis negative 1 comma 1 right-parenthesis, the third point is graphed at left-parenthesis negative 1 comma negative 1 right-parenthesis, the fourth point is graphed at left-parenthesis 1 comma 1 right-parenthesis, and the fifth point is graphed at left-parenthesis 2 comma 2 right-parenthesis.

A parabola is graphed on a coordinate plane. Its vertex is at left parenthesis 0 comma 0 right parenthesis and the parabola opens to the right. It also passes through the points left parenthesis 4 comma 2 right parenthesis, left parenthesis 1 comma 1 right parenthesis, left parenthesis 1 comma negative 1 right parenthesis, and left parenthesis 4 comma negative 2 right parenthesis.

A coordinate plane is shown. A single line runs from Quadrant Two to Quadrant Four. The line runs through the origin at left parenthesis 0 comma 0 right parenthesis.
The correct graph that represents a function is:
A coordinate plane is shown. There are five points on the graph at (-2, 2), (-1, 1), (-1, -1), (1, 1), and (2, 2). The y-axis goes from -5 to 5. The x-axis also goes from -5 to 5. The first point is graphed at (-2, 2), the second point is graphed at (-1, 1), the third point is graphed at (-1, -1), the fourth point is graphed at (1, 1), and the fifth point is graphed at (2, 2).
