The question:

The function $\displaystyle f(x) = \frac{x - 2}{x^2 - 3x + 2}$ is not defined for x = 2. Find a value to be given to f(2) that will make f continuous at 2.

I'm not sure what this question is asking of me. Perhaps it's how it's worded, but I'm completely stumped. Any suggestions? Thanks.
