x + 3
Help please?
Thank you
Answer by Alwayscheerful(414)   (Show Source):
You can put this solution on YOUR website! The domain of a function is the values of x
If the denominator is zero, the function will be undefined.
So in this case, the domain can't equal zero, so x cannot be -3.
Every other number works in this function except -3.
So, we can say that the domain of this function is "all read numbers except -3".
Hope this helps!
