Important note in answer
Note the use of different bracket styles in domain and range intervals
A square bracket, [ implies that the value adjacent to it is included A regular bracket(parenthesis) implies that the value next to it is not included.
So for domain, the value -4 is included but not ∞
For range, the value -∞ is not included but the value 3 is included
Definition of domain and range
The domain of a graph consists of all the input values shown on the
x-axis. The range is the set of possible output values, which are shown on the y-axis.
