More Calculus help please! Limits…?
a) Use the values of 4.1, 4.01, 4.001 to guess at the value of
lim [ x^(3/2)-8]/(x-4)
(x–>4)
***the values I got were 3.0187, 3.00187, and 3.00187 – so I guess that as x approaches 4, limit approaches 3… is this what it’s asking?
b) Using an appropriate factorization, find the limit in a)
**Don’t know how to start on this one…
Thanks in advance!

(a). Correct
(b)
[x^(3/2) – 8] / [x-4]
= [x+2*Sqrt(x) + 4] / [Sqrt(x) + 2]
So plug in 4 now
[4 + 2*2 + 4] / [2 + 2]
= 12/4 = 3
