Question

find the domain and the range of the following relation. also d

choose the range below.
a. ( 50^circ ) to ( 257^circ )
b. ( {20^circ, 10^circ, 125^circ, 110^circ} )
c. ( {68^circ, 50^circ, 257^circ, 230^circ} )
d. none of the above

is the relation a function?
yes
no

Explanation:

For the range of a relation, the range consists of the output (dependent) values. Option B has a set of angle measures which are likely the range values (outputs). Option A is an interval, not a set of discrete values. Option C seems more like domain values (inputs). So B is correct. For the function question, if each input (domain) has exactly one output (range), it's a function. Since the selection for range and the function check (Yes) aligns if each domain element maps to one range element.

Answer:

B. $\{20^\circ, 10^\circ, 125^\circ, 110^\circ\}$
Yes (for "Is the relation a function?")
