Question: how to find square roots of a function?
Answer: Note that the domain of f(x)=√x is x≥0 and the range is y≥0 .
The graph of f(x)=√x−a+b can be obtained by translating the graph of f(x)=√x to a units to the right and then b units up.
Step 2: Move the graph of y=√x by 1 unit to the right to obtain the graph of y=√x−1 .
