Question 599399: Write domain
5/k+2
Answer by nerdybill(7384)   (Show Source):
You can put this solution on YOUR website! The "domain" specifies all valid values of k.
For
5/(k+2)
The only value that k can't be is when the denominator is zero (can't divide by zero) that value is:
k+2 = 0
k = -2
That is the ONLY value k can't be
so the domain is
"all real number except for -2"
OR
(-oo, -2) U (-2, +oo)
where
oo stands for infinity
