Determine which graph shows y as a function of x. coordinate plane with a vertical line going through the x axis at 3.

Coordinate grid. y axis numbered from negative 4 to 4 in increments of 1. X axis numbered from negative 5 to 5 in increments of 1. Graph of an equation passing through point 2 comma 2, negative 2 comma zero and 2 comma negative 2

A circle on a coordinate plane centered at the point begin ordered pair negative 2 comma negative 3 end ordered pair. The circle passes through point begin ordered pair negative 2 comma 2 end ordered pair.

4 quadrant coordinate graph. The x-axis and y-axis are labeled from negative 5 to 5 with each square representing 1 unit. A horizontal line is drawn through the y-axis at 4.
