Question

If ƒ = {(5, 1),(6, 2),(7, 3),(8, 1),(9, 7)}, then the range of ƒ is?
A. {(1, 5),(2, 6),(3, 7),(1, 8),(7, 9)}
B. {1, 2, 3, 7}
C. {5, 6, 7, 8, 9}

Answer 1

Domain = all x values
Range = all y values

But when listing all the values, you should never list the same number twice even if there is two of the same in the set given

Answer 2

Say we have the data set (3, 4) (5, 2) (3, 2) (6, 1) and we need to find the range. First, list all the y values in least to greatest order.

1, 2, 2, 4

Now take out any of the repeating numbers

1, 2, 4

So our range for the data set (3, 4) (5, 2) (3, 2) (6, 1) is
{1, 2, 4}

Answer 3

A. {(1, 5),(2, 6),(3, 7),(1, 8),(7, 9)}
B. {1, 2, 3, 7}
C. {5, 6, 7, 8, 9}

Answer 4

So with that info given, what do you think it is?
