Posted on 2015-09-21 05:58:00 in Math by LYON

I'm stuck on this general concept, Here's a couple of questions I need help with. If you could explain any of them review how to get the answer. that would really help me out.

lim x->16 ( (sqrt(x)) - 4 ) / (x-16) =

lim x->pi sin(3x/2) =

lim x->infinity ( 4x^(2) - 2x - 1 ) / ( -2x^(2) + 1)

lim x->3 (-5) / ( (x-3)^(2) )

lim x-> -1 ( 3x^(2) + 5x - 2 ) / (x+2)

lim x-> -2 Sqrt ( (x+2)/(x^(2)+4x+4) )

Anything you can point out helps! thanks!
