Multiple Choice

Let T be the relation in the set N given by T = {(a, b) : a = b + 1, b > 10}. Which of the following statements are correct?

Domain: {x : x ≥ 9}

Domain: {x : x ≥ 10}

Domain: {x : x > 12}

Domain: {x : x ≥ 12}

Multiple Choice

What are the domain and range of the relation {(5, 3), (−1, 3), (−5, 1)}? Is the relation a function? Choose yes or no.

D = {−5, −1, 5}; R = {3, 1}; no

D = {3, 1}; R = {5, −1, −5}; no

D = {3, 1}; R = {5, −1, −5}; yes

D = {−5, −1, 5}; R = {1, 3}; yes

Multiple Choice

Consider set A = {4, 5, 7, 10} and set B = {5, 10, 16, 20, 24}, where a ∈ A and b ∈ B. Which of the following is the set of the ordered pairs when ‘b’ is multiple of ‘a’ and a < b?

{(4, 16), (4, 20), (4, 24), (5, 5), (5, 10), (5, 20), (10, 10), (10, 20)}

{(4, 16), (4, 20), (4, 24), (5, 10), (5, 20), (10, 20)}

{(4, 16), (4, 20), (4, 24), (5, 10), (5, 20), (7, 24), (10, 20)}

{(10, 5), (16, 4), (20, 10), (20, 5), (20, 4), (24, 4)}

Function Notation

Some sets of ordered pairs can be described by using an equation. When the set of ordered pairs described by an equation satisfies the definition of a function, the equation can be written in function notation.
