y=sqr(x-7)

The function you provided is \( y = \sqrt{x-7} \), which represents a square root function. This function takes an input (x) and subtracts 7 from it before finding the square root. The graph of this function will start at (7,0) and increase as x increases. The domain of this function is x ≥ 7, and the range is y ≥ 0. If you have any specific questions or need further assistance, feel free to ask!
