Question

Is the equation below a function or not ? Explain

`f(x)=x^3-4x^2`

Answer 1

Yes.

Explanation:

This is a function because it passes the "vertical line test" that means that for each input in its domain there is only one unique output in its range so it meets the criteria for a function. Its inverse is not a function.
