Answer 1

The domain of the given graph is:

-10 < x ≤ 2

What is the domain of this function?

The domain is the set of possible inputs that a function has. To identify the domain, we just need to look at the horizontal axis.

To find the domain we need to look at the horizontal axis.

The leftmost value is x = -10

The rightmost value is x = 2

Notice that the leftmost one has a open circle on it, which means that it does not belong to the domain, while the rightmost has a closed circle, which means that the value belongs to the domain.

Then the domain is:

-10 < x ≤ 2
