Which graph represents y as a function of x? Graph of a vertical line passing through the x-axis at 6.

The graph of two rays on a coordinate plane. Both rays have endpoints at 0 comma 1. One ray goes through 5 comma 4 and 10 comma 7. The other goes through 11 comma negative 5 and 1.83 comma 0.

A coordinate plane with axes labeled x and f of x. A ray with a closed endpoint at ordered pair 1 comma negative 4 extends to the left through ordered pair negative 5 comma negative 4. A ray with a closed endpoint at ordered pair 1 comma 4 extends to the right through ordered pair 5 comma 4.

4 quadrant coordinate graph. V-shaped line with vertex at the origin opening upwards.
