based on the graph below, how would you describe the curve?

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:
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.
