Which graph represents the piecewise function? y={x−4 if x≤0−2x if x> 0

two rays on a coordinate plane with axes labeled x and y. one ray starts with an open circle at 0 comma negative 4 and extends through negative 5 comma negative 9. the other ray starts with a closed circle at 0 comma 0 and extends through 5 comma negative 10.
