Question

ANGE to get FULL credit, Warm Up Write a rule for each function. Then state the domain and range. 1. {(3,-3). (4. -4). (6.-6).(-7.7)} 2. {(0,0), (4,12). (2.6),(-1.–3)} 3. (2.1). (8.4), (-6.-3). (1.)} 4. {(8.7.), (0.-1). (4.3).(-1.–2))

Answer 1

We want to find the domain and the range for the function:

$\mleft\lbrace(3,-3),(4,-4),(6,-6),(-7,7)\mright\rbrace$

We remember that the domain of a function is the set of all values that the independent variable takes, and the range of a function is the set of all values that the dependent varialble takes. In this case, the independent variable is x, and the dependent one is y.
