Question

lim f(x) is f(x) = {3, x an integer; 1, otherwise} as x-->2

Answer 1

It's telling me the answer is 1. Is 2 not an integer?

Answer 2

ok, x->2 means x is very near to 2 but not equal to 2.
2 is an integer,but here x isn't.
like x can take values, 1.99999 or 2.000001
ok?

Answer 3

did u get it @cuzzin ?

Answer 4

Ah, ok, so because x is only approaching the value 2, but not exactly 2, it is not an integer, right?

Answer 5

yup,exactly
