Domain and Range Examples: Medium
1)To see pictures bigger click on them
The domain is (-∞,∞) and the range is (-∞,∞)
They are both the same because on both sides of the graph it is going towards ∞ or -∞ and because it is ∞ it is notated with ( or )

They are both the same because on both sides of the graph it is going towards ∞ or -∞ and because it is ∞ it is notated with ( or )
2)
The domain is [-4,∞) and the range is (-∞,∞)
On the x-axis the farthest left that it goes is -4 and because it actually goes to that point and stops right there it is notated with [ or ]
Because the y-axis goes to both -∞ and ∞ on the right side it is notated with ( or )
