If f(x) = (x - B)/(x - A), f(2) = 0, and f(1) is UNDEFINED, what are the values for A and B? NOTE: Does the word UNDEFINED mean DOES NOT EXIST because division by zero is IMPOSSIBLE?

As you know f(x) in this case is zero when (x-B) is zero so if f(2)=0, then substitute 2 for x in (x-B)=0, to find B=2. Also if f(x) is undefined (x-A) is zero, and so if f(1) is undefined substitute 1 for x in (x-A)=0, to find A=1. RonL
I think it's an interesting question. Thanks!
