Answer:

Option B

Step-by-step explanation:

we have

f(x)=x^{3}-x^{2}-9x+9

we know that

<u>The vertical line test </u>is a visual way to determine if a curve is a function or not. A function can only have one value of y for each unique value of x

In this problem

The given function  passes the vertical line test

therefore

f(x) is a function

<u>The Horizontal Line Test</u>  is a test use to determine if a function is one-to-one

If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.

In this problem

The given function fails the horizontal line test

because for f(x)=0 x=-3, x=-1, x=3

therefore

It is no a one-to-one function
