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

Determine Domain and Range from a Graph | College Algebra
Given the graph, identify the domain and range using interval notation. ... Yes. For example, the domain and range of the cube root function are both the set of all real numbers. We will now return to our set of toolkit functions to determine the domain and range of each.

How do you find the domain of a graph?
Analyze the graph from left to right. Every x-value that has a corresponding y-value on the graph is in the domain of the function. If there is no corresponding -value, then that -value is not in the domain.

What is the domain of a function?
The domain of a function are all the values that the function is defined for. If the independent variable is time, distance, quantity, etc., that will limit the domain to only positive numbers and zero.

April 9, 2024 - For our first example, we are given the graph of the function f(x)=x^2 and we are tasked with finding the domain and the range (note that our answers must be in interval notation). Figure 08: Find the domain and range of the graph of y=x^2. Remember that the domain refers to all of the possible x-values, and the range refers to all of the possible y-values. Let’s start with finding the domain of this graph. Notice that the graph is a parabola that extends forever on both the left and right-side of zero.

Click on "Rain" or "Squish" in the graph below to watch the animation for finding the domain. Notice that the graph always goes towards the \(x\)-axis. So, the parts of the graph below the axis actually go up towards the axis. From the animation, you'll see that the domain of this function is \((-6,-1]\cup[3,7]\text{.}\) If you want to see the animation in a larger window, click here 2 .
