Specify the domain of each variable.
1. ax + b
Here, x is the variable. I say a and b are constants.
Therefore, the domain is ALL REAL NUMBERS.
Is this right?
2. ax^(1/3) + b
Again, x is the variable. I know that a and b are constants.
I decided to rewrite question 2 as a*cuberoot (x) + b. Is this correct? What would be the domain in this case?
