Answer:
[tex](\infty,-\infty)[/tex]; All real numbers.
Step-by-step explanation:
We have been given an equation [tex]y=-x^2-6x-13[/tex]. We are asked to find the domain of the given equation.
We know that domain of a function is the values of x, for which our function is defined.
Since our given function has no undefined points or domain constraints, therefore, the domain of our given function is all real values of x. In interval notation the domain of our function would be: [tex](\infty,-\infty)[/tex].
