Answer:
D. [tex]x\leq 0[/tex].
Step-by-step explanation:
We have been given graph of a function. We are asked to find the domain of our given function.
We know that domain of a function is set of values of independent variable (x) for which our function is defined or have a specific y-value.
Upon looking at our given function, we can see that our given function is defined for all values of x less than or equal to 0, therefore, domain of our given function is [tex]x\leq 0[/tex] and option D is the correct choice.
