Homework Statement Determine the value of b so that each limit exists. lim (4x^2 + 11x -3) / (x-b) x->b Homework Equations The Attempt at a Solution I factored it to (4x-1)(x+3) / (x-b) but still not too sure what else to do.

Alright. Once I find x, what do I do with it?. Btw, the slope for that line is (x-1)/(x^2+6) rite?
