ANSWER
[tex](-\infty,\infty)[/tex]EXPLANATION
We want to find the domain of the function using interval notation:
[tex]f(x)=-2x(x-3)(x-6)[/tex]The domain of a function is the set of all input values of a function i.e. the set of all x values for which a function is valid.
For the given function, all real values of x satisfy the equation.
This implies that the domain of the function is:
[tex](-\infty,\infty)[/tex]That is the answer.
