Question

(x^2-3x+2)/(x-4)
Find the limit as x approaches 4

Answer 1

my first instinct was that because 4-4=0 it would become undefined, thus for small values in the denominator it would make it infinity big. What is the actual limit here? Help please ! :)

Answer 2

Whenever you have limits of rational functions, you have to factor it.

Answer 3

even after I factor I don't see much else to do?
