    The graph can be split up into four regions:

    • When x < −2, the graph of the square root function will be undefined.
    • When −2 < x < 0, the y-value of the graph of the square root function will be greater than the y-value of the original graph.
    • When x > 0, the y-value of the graph of the square root function will be less than the y-value of the original graph.
    • When x = −2 and x = 0, the two graphs have the same y-value (they are invariant points).

    This should result in a graph that looks as follows:

     

    This graphic shows the graphs of two functions. One graph is the function y equals h brackets x brackets. The other one is the function y equals begin the square root h bracket x bracket and the end of the square root. The graphs have points of intersection at (-2, 0) and (0, 1).
