Question

Which statement best describes the function below?

f(x)=2x^3+2x^2-x

A. It is not a function.
B. It is a many-to-one function.
C. It is a one-to-one function.
D.It fails the vertical line test.

Is it B??

Answer 1

well it's a function so A is wrong. it's not a one-to-one because that would be linear and this function is definitely not linear so C is wrong. D is wrong too because it's a function so it passes the vertical line test.

Therefore, B is logical
