Question

find the limit: lim f(x) f(x)=x^2+2, x doesn't=1
x-->1 1, x=1

Answer 1

plug in 1

Answer 2

to x^2 +2?

Answer 3

err \[\lim_{x \rightarrow 1} x^2+2\]

Answer 4

is that the question?

Answer 5

yeah

Answer 6

yes because we have no problems with the domain you can plug in 1 and you will get the answer....3

Answer 7

note: if we would have had this

\[\lim_{x \rightarrow 1} \frac{ x^2 }{ 1-x }\]

then you could not just "plug in" one because then you would be deviding by 0

Answer 8

oh ok THANKS. :)
