A For every $\epsilon>0$ there is a $x$, so that $\lvert f(x)-f(13) \rvert<\epsilon.$ B For every $\epsilon>0$ there is a $y$, so that $\lvert f(x)-13 \rvert<\epsilon$ for all $x<y.$ C For every $\epsilon>0$ there is a $x$, so that $\lvert f(x)-13 \rvert<\epsilon.$ D For every $\epsilon>0$ there is a $y$, so that $\lvert f(x)-13 \rvert<\epsilon$ for all $x>y.$

A For every $\epsilon>0$ there is a $\delta>0$ and a $x$ with $\lvert x--2 \rvert<\delta$ and $\lvert f(x)-3 \rvert<\epsilon.$ B There is an $\epsilon>0$ and a $\delta>0$, so that $\lvert f(x)-3 \rvert<\epsilon$ for all $x$ with $\lvert x--2 \rvert<\delta.$ C For every $\epsilon>0$ there is a $\delta>0$, so that $\lvert f(x)-3 \rvert<\epsilon$ for all $x$ with $\lvert x--2\rvert<\delta.$ D There is an $\epsilon>0$, a $\delta>0$ and a $x$ with $\lvert x--2 \rvert<\delta$ and $\lvert f(x)-3 \rvert<\epsilon.$
