In the function , the parameter a controls the vertical stretch or compression and reflection of the graph of the square root function.
If |a|>1, the graph of the function stretches vertically (it becomes "steeper").
If 0<|a|<1, the graph compresses vertically (it becomes "flatter").
If a<0, the graph reflects across the x-axis.
