Question

how do i calculate the following limits, if they exist.
if they dont exist how do i explain why not?

lim as x ->2 of x^2-4/x-2

Answer 1

First, you work on your algebra. You seem to have forgotten your Order of Operations.

You have written \(x^{2} - \dfrac{4}{x} - 2\)

If that is NOT what you intended, use parentheses appropriately to fix it.
