Question

Is the function shown in the graph one-to-one?

Answer 1

In the given diagram , the graph is a straight line and for every x value the y value is same.

And for a function to be one-to-one, there exist one output for different inputs .

So the given function is not one-to-one and the correct option is the first option .

Answer 2

Answer:

→A function is said to be one-one, if for each distinct input there is distinct output.

→In the graph given below, the function is

 f(x)=c

→For each distinct input ,there is single output.

So, the function is not one -one.

Option A

No, there exists more than one input for at least one output.
