what is the domain of the function below?

Question

{(0,2)},(3,1),(5,2),(8,4)}?

a. {1,2,4}
b. {0,3,5,8}
c. {0,1,2,3,4,5,8}
d. {(0,2),(3,1),(5,2),(8,4)} *****

Is the following relation a function? {(0.3,0.6),(0.4,0.8),(0.3,0.7),(0.5,0.5)}
a. yes
b. no *****
c. cannot be determined

Answer 1

The domain is the set of 1st values from the pairs: (b)

In #2 you are correct.

Answer 2

The Domain = all x values... so in a coordinated pairs above (x,y) the domain = {0,3,5,8}
the Range would = all y values.
The definition of a function is that a function is a correspondence between a first set, called the domain (x values), and a second set, called the range (y values), such that each member of the domain corresponds to exactly one member of the range. So basically if any number is seen more than once in the domain... it's not a function.
b would be correct for the first question
b would be correct for the second question.
