Determine whether the following graph represents a function.

Answer:
Step-by-step explanation:
Draw a vertical line on top of this graph. Note that this line will intersect the graph in only one place. Thus, the criterion for the existence of a function is satisfied; the given graph IS that of a function.
Answer:
Step-by-step explanation:
As, if we draw a vertical line anywhere on the graph it doesn't passes more than one point.
Hence, it's a function.
