What is the range of the given table?

A. The range is { 1, 2, 3, 4 }.
Incorrect. This is the domain.

B. The range is {1,2, 3 .... }.
Incorrect. This range is discrete.

C. The range is { 1, 3, 5, 7 }.
Correct! This is the range.

D. The range is { 1 , 2, 3, 4, 5, 6, 7, 8 }.
Incorrect. This set if all whole numbers less than 9.


Given the set { ( 3, 4 ), ( 4, 9 ), (-5 , 6 ), ( 0 , 2 )}, determine the domain.

A. D: { 2, 4, 6, 9 }
Incorrect. This is the range.

B. D: { -5, 0, 2, 3, 4, 6, 9 }
Incorrect. This response is all numbers.

C. D: { -5, 0, 3, 4}
Correct! This is the domain.

D. D: { -5 }
Incorrect. The interval notation should include all numbers between the constraints.


What are the domain and range of the mapping diagram below?

A. D: {all real numbers}; R: {all real numbers}
Incorrect. The domain and range are not infinite sets.

B. D: { -6, 0, 2, 3, 6, 8}; R: { -6, 0, 2, 3, 6, 8}
Incorrect. This response repeats all members of both domain and range.

C. D: { -6 < x < 8}; R: { -6 < y < 8}
Incorrect. This interval notation includes all numbers.

D. D: { -3, 0, 2, 3}, R: { -6, 0, 6, 8}
Correct! The domain is the set of input values and the range is the set of output values.


List the domain and range in set notation from the table of values below.

x
y
38
50
75
125
182
274

A. D = { 50, 125, 274 } R = { 38, 75, 182 }
Incorrect. You reversed the domain and range.

B. D = { 38, 75, 182 } R = { 50, 125, 274 }
Correct! The domain is the x-values and the range is the y-values.

C. D = { all real numbers } R = { all real numbers }
Incorrect. The domain and range are discrete sets.

D. D = {38, 50, 75, 125, 182, 274 } R = { 38, 50, 75, 125, 182, 274 }
Incorrect. You picked a domain and range that include all the numbers.
