Question

Is the statement true: `f(x)=x^3`?

Answer 1

Yes this is a function.

Explanation:

Yes it is a function, looking at the graph; it passes the "Vertical Line Test" which is: for each value of `x` (the domain) there is only one returned `y` value (the range):

remember the horizontal axis is `x` and the vertical axis is `y`.
