lim
y→−1 (sqrt(y^2+8)3)/y+3
find limit if it exists
please help

calculus please help 
Reiny,
step #1 in any limit question is to simply sub in your approach value.
If you get a real number answer, that's it, that's your answer, you are done!
lim ( (√(y^2 + 8)  3)/(y+3) , y >1
= ( √9  3)/2
= 0/2
= 0
