This Khan Academy video offers more information on graphing square root functions and contains a few sample problems with a step-by-step walkthrough on graphing these functions.
Graphs Of Square Root Functions is a free educational video by Khan Academy.It helps students in grades HS practice the following standards HSF.BF.B.3.
1. HSF.BF.B.3 : Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
