If you know the "parent" graph and some key features about the graph of y = root (x), then you can use transformation rules to sketch other square root functions. Here we look at vertical stretches and compressions that are caused by multiplying the root by some value. If the (absolute value of) the multiplier is greater than one, then we have a vertical stretch, whereas if the (absolute value) of the multiplier is a fraction between zero and one, then we have a vertical compression. We also consider what this does to our domain (inputs) and range (outputs).
