Answer:
[-2,infinitysymbol)
Explanation:
If you have a graph to look at, the domain is like you are walking up and down the x-axis (which is actually not up/down but left/right) and you're stating where this graph exists.
If you walked all the way over to -10 and looked up or down, the graph just doesn't exist over there.
The graph exists from -2, including -2, so use the SQUARE bracket [.
On the right side there's an arrow on the graph so it keeps going forever. Thats infinitysymbol.
Always wrap a parenthesis ), around the infinity symbol.
Interval notation uses the [SQUARE] brackets or (parenthesis) and even though it looks like a point, its not. It means
[FromHere, ToHere) and answers the question, where is the graph?
