Which relations are functions? Select Function or Not a function for each graph. Function Not a function A graph of a linear equation on a coordinate plane. The horizontal x axis ranges from negative 5 to 5 in increments of 1. The vertical y axis ranges from negative 5 to 5 in increments of 1. A solid line passes through the origin, begin ordered pair negative 2 comma 4 end ordered pair, and begin order pair 2 comma negative 4 end ordered pair. Function â€" Not a function â€" A cubic graphed on a coordinate plane. An s-shaped curve with a turning point at the origin is graphed. Moving from left to right, the graph increases through the third quadrant, turns right and passes through the origin, then turns upward and increases through the first quadrant. Function â€" Not a function â€" Graph of a line on a coordinate plane. The horizontal x axis ranges from negative 5 to 5 in increments of 1. The vertical y axis ranges from negative 5 to 5 in increments of 1. A line parallel to the y axis passes through begin ordered pair 3 comma 0 end ordered pair. Function â€" Not a function â€" A parabola graphed on a coordinate plane. The x-axis ranges from negative 5 to 5 in increments of 1. The y-axis ranges from negative 5 to 5 in increments of 1. The vertex of the parabola is at the origin. The parabola opens to the right and passes through the points begin ordered pair 4 comma 2 end ordered pair and begin ordered pair 4 comma negative 2 end ordered pair. Function â€" Not a function â€".
