What is the domain of the function $w(x) = \sqrt{x - 2} + \sqrt[3]{x - 2}$? Express your answer in interval notation.

We only need  worry about  the  first function........x can be any  real value in the second

 

Since we  can't  have  a negative under  a square root,  the  domain of  the  first function  is  [ 2, infinity )

 

And we  must take the most restrictive domain....so.....   [ 2, infinity)
