Step-by-step explanation:

Concept:

To figure out if a graph is a function, we will use the vertical line test below

The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines.

From the first graph we can see that the vertical line cuts the points at on intersection

The Second graph is given below as

Its has two intersections on both sides of the graph

The third graph is given below as

It has two intersections on the ride hand side of the graph

The Fourth graph ios given below as

Its has two intersection on the right hand side of the graph

In conclusion,

A graph is said to be a function if one value of x has a separate value of y

Therefore,

The final answer is

The FIRST OPTION is the correct answer
