f(x)=(x^2-9)/(x-3), if x=/=3
f(x)=4, if x=3
lim f(x) x->3=?
It says the answer is 6. I don't understand how it isn't 4?
Hopefully that jumble of variables will make sense to someone.
That is what I did for x->3+ and x->3- and I got 6
I thought it would be different if it wasn't approaching from the left or right though.
