    \(x^2\) is not going to be negative. The least \(x^2\) can be equivalent to is 0 (when x=0).

    And as \(x\) tends \({\rm infinity}\), \(x^2\) all the more so tends to \({\rm infinity}\).

    So it is going to start from 0, and go into infinity. So your answer is?

    All real numbers are fractions, square roots, integers, ((and basically all numerical quantities which are not undefined and that don't contain \(i\) (imaginary number that you might not have studied)))
