Graphing the endpoint of the domain tells us where the graph starts, and graphing a few more points helps us to see the approximate shape of the curve before we draw it. Plot some points – this helps us to know where to sketch the square root curve in the next step. That means we must solve the inequality that makes the radicand greater than or equal to zero. Remember that the square root of a negative is imaginary, so we can’t graph it in a 2D real number system. Find the domain– this tells us where the graph of the square root function will be defined.

To graph a square root function, there are 4 steps we can take to break down the process: We’ll also take a look at several examples, showing the steps as we go along.

In this article, we’ll talk about how to graph any square root function. Also, you need to know the general shape of a square root function and how it changes with different signs. Of course, a table of values can help you with graphing your first few points. Finally, connect the points by sketching the shape of the square root function. Then, pay attention to negative signs, which can “flip” the graph across a line. Next, plot some points on the graph, including the one at the end of the domain. So, how do you graph a square root function? First, find the domain – the radicand cannot be negative. It is a good idea to know how to graph square roots and other radicals (either to draw them by hand or to verify what a calculator is showing you). Square root functions come up in algebra, pre-calculus, calculus, and other subjects.
