    Easy limit problem

    Hi!

     \mbox{Show that} \ lim_{x \rightarrow  3} \ \ x^2 \ = 9

    Please help me through this.

    For every  \epsilon > 0 \ \mbox{there is a } \delta >0  \mbox{such that} \ \mid f(x) - A \mid < \epsilon \ \ \  \ \ \ \ \Rightarrow \mid x - a \mid < \delta

    This is delta-epsilon definition, right?

    How should I start?

    Thanks!
