(1 point) Suppose y = x- V7 - x. List the endpoints of the domain. Endpoints are (Enter the endpoints as a comma-separated list. If there are no endpoints, enter "none".) List the critical points. Critical points are (Enter the critical points as a comma-separated list. If there are no critical points, enter "none".) Find the absolute maximum value. Absolute maximum value is (If there is no absolute maximum value, enter "none".) Find the absolute minimum value. Absolute minimum value is (If there is no absolute minimum value, enter "none".) Find all relative maximum values. Relative maximum values are (Enter the values as a comma-separated list. If there are none, enter "none".) Find all relative minimum values. Relative minimum values are (Enter the values as a comma-separated list. If there are none, enter "none".)
