Given:
The graph is:
Find-:
The graph represents the function
Explanation-:
From the first graph
At x is 2 value of y is -3 and -1 so at one value of two value of y is not possible so it is not a function
For the second graph
At x= 4 value of y is -3 and 4 so at one value of two value of y is not possible so it is not a function
For the third function:
All values of x is a different value of y so it is a function.
So the answer is the third graph.
