Use the graph to determine the domain and range of the relation, and whether the relation is a function.

a. Domain: {xl-8, 8}; Range: all real numbers; No, it is not a function.
b. Domain: {x-8 SX s 8}; Range: all real numbers; Yes, it is a function.
c. Domain: {x| -8 < X < 8}; Range: all real numbers; No, it is not a function.
d. Domain: {x| -8 < X 8}; Range: {yl -12 sx s 12); Yes, it is a function.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

if i put something wrong your not gonna like it so rather not say nothing.
