Which is the following best describes the graph below?

A. it is many-to-one function

B. it is a function but it is not one to one.

C. it is a one to one function

D. it is not a function

Answer 1

it is not a function because it touches the graph

Answer 2

we are given with a graph and we have been asked to find Which of the given options best describes the graph ?

As we know from the vertical line test of a function that a curve reprsents a function , if we draw a vertical line and that line intersect that curve only once.

If that vertical line interscet the given curve more than once it mean that curve does not represent a function.

Here for the given curve if we will draw any vertical line, that line will intersect it more than once.

Hence the given curve does not represent a fimction.

Hence the correct option is D.
