Question 527336: find the domain of the given function
f(y)= 1/(y+1)

You can put this solution on YOUR website!
You cannot divide by zero

So y+1 cannot be zero


If it were, then y + 1 = 0, which would mean that y = -1


So if y = -1, then y + 1 = 0, which would cause a division by zero error.


To avoid this, we exclude this value from the domain.


So the domain is the set of all real numbers, but y cannot equal -1.
