Notes: 1) When you're expressing equivalence of two statements, avoid using "=" sign. You may use either "iff" (short for "if and only if") or "is equivalent to" instead of the equal sign.

2) In questions related to the definitions of limit of a function and the continuity of a function, you may use any of the interval notations, [a,b] (closed interval), (a,b) (open interval), and [a,b) and (a,b] (half-open intervals). You can use it as follows:
For every x in (0,infinity) [x^2 > 0]
You don't need to add the expression "x in R", as the interval notation refers to the real numbers between a and b (including or excluding the endpoints depending on the interval being closed or open) by default.
