Question

Which of the following graphs represents a function?

Answer 1

Answer:

The last one

Step-by-step explanation:

If you look at a graph, none of the line should overlap each other vertically. If a graph overlaps anywhere vertically, it is not a function.

Answer 2

Answer: Third graph is the correct choice.

Step-by-step explanation:

Since we have given figures

We need to find the graph which is a function.

For being a function , it should satisfy the condition mentioned below :

If we draw a vertical line which intersect the graph more than once, then it is not considered to be function as there will be more than one values for x .

According to options , only third graph satisfy the condition when we draw a vertical line intersecting the graph.

There will be only one value of y for each x.

Hence, third graph is the correct choice.
