What is the domain of f?

Domain: [-5 , 6] OR can also be written as

{x | -5 <= x >= 6}

OR The domain of x is from -5 to 6, including -5 and 6

Step-by-step explanation:

The domain is all the x's on the graph or if you have an equation, all the x's that are allowed to go into that equation. The graph you shared starts at -5 (if you're looking at the x-axis) and goes all the way to 6 (again, on the x-axis) They have a solid, colored in dot on the endpoints so we include the -5 at the beginning and the 6 at the end.
