Add a zero to each of the end of them
Answer: The system consists of parallel lines
Step-by-step explanation:
Given system of lines :

Substitute
in
, we get
, which is not true.
That means , system has no solution.
i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]

Answer:
D_{f(x)} = [9, \infty)
Step-by-step explanation:
Here we have the square root of a function, in the following format:

For the square root, and roots of even numbers(root of 4, 6, ...), we have the following condition in the domain

In this problem, we have that:

So


So the domain is
