""Rob, let me ask you something. Consider the polynomial fraction (x-1)/[(x-2)(x-3)]. What is the value of this fraction as x becomes infinitely large (in the dedicated lingo as x tends/goes to infinity)?"

"The answer is 1,"
"The answer is 0, because the question is implicitly asking for a limit."

"if x = infinity."

X can never equal infinity. That's why we use the clumsy limit notation instead of just writing infinity in for those variables.


"I don't know what it is when x is infinitely large."

I don't understand the distinction between x being equal to infinity and x being infinitely large. This stuff is not actually calculus at this point. So far this is stuff that's covered pretty thoroughly near the end of algebra II.
