(a) Note: y is not defined for values of x less than -1
Hence, x < -1 is not in the domain
(b) determine the values in the table:
| x | -1 | 0 | 1 | 2 | 3 | 4 | 5 |
| y | 0 | 1 | 1.4 | 1.7 | 2 | 2.2 | 2.4 |
(c) The positive square root is indicated,hence, the range consists of all positive values of y, including 0 (ie. y ≥ 0)
