The range of the given function can be determined by comparing this with the graph of

The given function is a vertical shift down by 1. Hence its range would be (-1,

Alternatively, interchange x and y and find the domain of the new function. Accordingly, x=

The domain of this function is all real values of x greater than -1, that is (-1,
