Question

Hi, does anybody know how to solve

lim x – 3
------
x→2 I x – 3 I

where the absolute value of x - 3 is the denominator ? Thank You

Answer 1

most calc teachers will tell you you can just plug in the 2 here. some call this direct substitution. the question is more interesting if x approaches 3.

Answer 2

Thanks, I just realised I should have put in x approaches 3, not 2.
