Question

Using a vertical line test, is this the graph of a function.

Answer 1

Yes. This is a graph of a function.

Step-by-step explanation:

The vertical line test demands that the vertical line should not intersect the function more than once.

Now, drawing a vertical line through the function gives

The intersection point is given in yellow. We see that the function intersects the line only once; thereofre the graph given is that of a function.
