@HemerickLee, directly substituting works, you just have to consider what the greatest integer function gives you for values of x less than (but close to) 3.
-7 is the answer
But how would you know what the answer is even with the 3-
When u square a number assume it to b a whole no.
For the first limit, you find the greatest integer for values of \(x\) less than but close to 3, which would mean
Ok, then what would we have to do next
The other limit is pretty clear. \(x^2=9\) when \(x\to3\).
So 2-9 is?
-7................................. But for the first one then it would be 2 and the second on it would be -7 but then what would it be to the left
-7 .... as simple... dats wot i wrote earlier
I know but I needed to know how to work through it. Thank you @frnd and @SithsAndGiggles
