Step-by-step explanation:
B; This is the graph of a function; but it is not one-to-one
Step-by-step explanation:
If you use the vertical line test, you will see that it only touches once. That shows it is a function
Then you use the horizontal line test to see if it is a one-to-one function. It is not a one-to-one function because it touches the horizontal line twice.
It is not a linear function because it is not a straight line.
This leaves you with answer B
