Given the function f(x) by f(x) = (2x-2)/((x^2)+x-2) A) For what values of 'x' is f(x) discontinuous? B) At each point of discontinuity found in part A, determine whether f(x) has a limit and, if so, give the value of the limit. C) A rational function g(x)= a/(b+x) is such that g(x)=f(x) wherever f(x) is defined. Find the values of 'a' and 'b'. I think I figured out both part A and B, but part C is killing me. Any help would be great.
