Answer:
The correct option is;
Because the vertical line intercept the the graph more than once, the graph is of a relation but it is not a function
Explanation:
A function is a kind of relation that maps a given set of inputs unto a set of outputs such that each of the values of the input can be linked to only one value of the output, such that the input and outputs form a set of ordered pairs
Therefore, a relation which maps a given input to more than one output is not a function, as such, given that the line intercepts the vertical line twice, then for a given value of x, which is the input, there are more than one value of y, which is the output, as such the relation is not a function.
