There exists $\\epsilon > 0$ such that for every $\\delta > 0$, $|x - c| < \\delta$ and $|f(x) - L| \\ge \\epsilon$

For every $\\epsilon > 0$, for every $\\delta > 0$, $|x - c| \\ge \\delta$ or $|f(x) - L| \\ge \\epsilon$

There exists $\\epsilon > 0$ such that there exists $\\delta > 0$, $|x - c| < \\delta$ and $|f(x) - L| \\ge \\epsilon$

There exists $\\epsilon > 0$ such that for every $\\delta > 0$, if $|x - c| < \\delta$, then $|f(x) - L| \\ge \\epsilon$
