Question

Based on the graph below, how would you describe the curve?​

Answer 1

It's A.

Explanation:

For every value of x there is one value of y - we can draw a vertical line through any value of x and it will pass through only one value of y.

Therefore it is a one-to-one function.

Answer 2

Option A

Explanation:

The curve given is an increasing curve cutting x axis once and y axis once.

Any vertical line cuts only once the curve. Hence this is a function only.

We find that for every y in the range there is only one x corresponding to that.

Hence this curve is not a many to one curve. It is not linear because it is not a straight line. It is a function.

Hence only correct option is

a) The curve is a one to one function.
