7-98.

Find the domain and range for each of the relations graphed below.

1. Look in your notes, the glossary, or the index for definitions and examples of domain and range.

Domain: $(0, 1, 2)$
Range: $(−2, 0, 1)$

1. See part (a).

Domain: $-1 ≤ x ≤ 1$
Range: $-1 ≤ y ≤ 2$

1. Domain: $x ≤ 2$
Range: $y ≥ −2$

1. Domain: all real numbers
Range: $y ≥ −1$
