Answer:
{x∈R | , x∉Z}
Step-by-step explanation:
Given the function y=3tan(2/3x)
We know that tangent is a function that's continuous within it's domain but not continuous on all real numbers
Also, the roots of y=3tan(2/3x) is where n is an integer
Note that the domain of the function cannot be within
Therefore, {x∈R | , x∉Z}
