hi all, i'm confused about a continuity problem:
Given the function f defined by f(x)=(2x-2)/(x^2+x-2)
a) for what values of x is f(x) discontinuous?
so I understand that there is a removable discontinuity at x=1, and a nonremovable discontinuity at x=-2
b) At each point of disconitinuity found in part a, determine whether f(x) has a limit and, if so, give the value of the limit.
but how do you go about solving B?
Limits exist at a removable discontinuity; but no limit at a unremovable discontinuity.
