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

We can observe that the graph extends horizontally from [latex]-5[/latex] to the right without bound, so the domain is [latex]\left[-5,\infty \right)[/latex]. The vertical extent of the graph is all range values [latex]5[/latex] and below, so the range is [latex]\left(\mathrm{-\infty },5\right][/latex]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range. Find the domain and range of the function [latex]f[/latex].

December 22, 2022[8th grade Pre-Ap math] How do I get the domain and range of these graphs?
For the first graph, the arrows indicate the the graph continues on towards infinity along the x direction. That’s why it’s domain is all real numbers. The range can be obtained by finding the maximum which in this case is at y=4, and we can see the graph continues downward towards -inf so the range is less than or equal to 4. For the second graph, the dot is located at point (-5,-1) and we can see an upward arrow extending towards +inf in both x and y directions. Since the dot is hollow, it means that the points x = -5 and y = -1 are not included in the domain and range hence the domain of x>-5 and range y>-1. For the third graph, just find where the edges of the oval line up. In this case there is an edge at (0,-0.5), one at (2.5,3), another at (5,-0.5) and a final one at (2.5,-4). This means that the domain is from 0 to 5 and the range is from -4 to 3. More on reddit.com
