You can put this solution on YOUR website! domain of a function?
---------------
Your domain is "all Real Numbers" because you can put any
Real Number you want to in place of "x".
------------------
You have a restriction on the domain if:
1) you are taking an even root of an expression with a variable in it;
like y = sqrt(x+2)
OR
2) you have a denominator with an expression with a variable in it:
like y = 3/(2x+1)
OR
3) you have a log expression like y = log2(x-3)
---------------
All of these cause you to have a restricted domain.
#1: x must be >= -2
#2: x must not be -1/2
#3: x must be > 3
