Graphing a function with a square root
WebSquare root functions will only do one or the other. The graph to the right is increasing only. It will increase when x ≥ 2 or in the interval [2, ∞). This will always match the domain. You will just need to determine if it is … WebTo show how this process makes sense, try graphing both y = sqrt (2x+3) and y = sqrt (2) * sqrt (x+3/2). You should get the same thing. To graph it, know what the graph of y = sqrt (x) looks like first (its a parabola on its side with only the top half).
