domain $[0,\infty) $ range $[-\infty, 1)$

Work Step by Step

Domain: All X values have to be positive. Any values for X that are not positive, thus being negative, will result in an imaginary number. Range: Insert the first domain value into the function, in this case, being 0, and get that value. The output will be 1. Any other values as X approaches infinity will be negative. They are negative because they are being subtracted from 1.
