You are a fighter jet pilot trying to land on a
carrier stationed off the Pacific coast.
You are 5000 feet from the arresting cables or
wires and still at an altitude 300 feet above the
ship's deck.

B. The graph is not a function.

Step-by-step explanation:

We are given the graph of a relation.

It is required to determine whether the graph represents a function or not.

'Vertical Line Test' states that,

'If a vertical line passing through the graph of the relation cuts the graph at at-most one point, then the given graph represents a function else not'.

So, if we plot the vertical line 'x = 3' in the figure, we see that,

The vertical line drawn crosses the graph at two points A and B as shown below.

Thus, the graph is not a function.
