1. lim (5/(2-x))
(coming from the right)'
5/(2-2) = 5/0
lim (5/(2-x)) = -infinite because...?
I know it equals negative infinite, but don't know how to show the work. I did a graph in my head...
2. What values of k is the function f(x) continuous on (-infinite, infinite)?
kx^2 + 14, x=>2
x + k^2 = ck^2 + 14
x + k^2 - ck^2 - 14 = 0.
Can somebody clear up these questions?
