Find the domain of the function #33. cuberoot. of 2t1 so do I say 2t  1 = 0 then 2t = 1 then t = 1/2 making the domain (infinity, 1/2) is this correct? #35. 1 / 4th root of x^2 5x so I factored and got x(x5) then I got x = 0 and x = 5 then I got D= (inf, 0)Union(5,infinity) is that right?

It's a reasonable guess that these questions are about real functions of a real variable, so the domain will be some subset of the reals, such as all the reals (which is what (infinity, infinity) amounts to).
