Determine whether the graph to the right represents a function. Explain. Does the graph represent a function? No, because there exists a horizontal line which intersects the graph at more than one point. Yes, because there exists a horizontal line which intersects the graph in at most one point. Yes, because there exists a vertical line which intersects the graph in at most one point. No, because there exists a vertical Iine which intersects the graph at more than one point.

Solution

A function can have only one output for unique input i.e the any vertical drawn anywhere on the graph shouldnt intersect the graph more than once. simply, for any value of \'x\' a function cannot have more than one value. so c is the right option
