For the Domain Hold a ruler, or some similar object, vertically on the left side of the graph. Now slowly move it to the right and mark down the intervals of x where the ruler would be crossing the graph. In this case, the graph heads to the left forever, so we start by thinking of x as -∞. As we move right, the graph is there until we hit x=-1 where there are those open circles indicating that no point exists there. So our first interval is (-∞, -1). As we continue, the ruler intersects the graph from just beyond -1 until we get to more open circles at x=4. So that interval is (-1, 4). After that the graph continues forever to the right which we write as ∞. So that interval is (4, ∞). Putting them together, we get... (-∞, -1) ∪ (-1, 4) ∪ (4, ∞) So the domain is every value of x from -∞ to ∞ except for -1 and 4. For the Range Do the same thing but in the vertical direction. Start with the ruler held horizontally at the bottom of the graph and move up while keeping track of the intervals of y where the ruler crosses the graph. Answer from Bascna on reddit.com

The output quantity is “thousands of barrels of oil per day,” which we represent with the variable [latex]b[/latex] for barrels. The graph may continue to the left and right beyond what is viewed, but based on the portion of the graph that is visible, we can determine the domain as [latex]1973\le t\le 2008[/latex] and the range as approximately [latex]180\le b\le 2010[/latex].
