Question

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

Answer 1

Answer:

It's A.

Step-by-step 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

Answer:

Option A

Step-by-step 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.
