WebJan 4, 2024 · Note the exact agreement with the graph of the square root function in Figure 1 (c). The sequence of graphs in Figure 2 also help us identify the domain and range of the square root function. In Figure 2 (a), the parabola opens outward indefinitely, both left and right. Consequently, the domain is. D f = ( − ∞, ∞) WebFor some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation …
