#### Answer:

Domain: all reals

Range:

#### Explanation:

When attempting to find the domain and range, it is best if you actually draw the diagram so you don't miss any points and when you are unsure. If you don't know what the graph looks like, just plot a bunch of points. But looking at the equation

graph{-2(x+1)^2-3 [-10, 10, -5, 5]}

So looking at the graph,

Domain: all reals

Range:
