{(2,2),(3,3),(4,4),(2,1)}


Use complete sentences to describe the relationship between sets A and B if A is a subset of or is equal to B.

A = {8}

B = {7, 8, 9}


Which of the following properties is a(b · c) = (a · b)c an example of?

associative property

commutative property

multiplicative identity

distributive property


Given: A = {a, e, i, o, u}, B = {a, l, g, e, b, r}, C = {m, y, t, h}, A ∩ C is

m, a, e, i, o, u, t, h

the empty set

i

a, e, i, o, u, y


If G = {(-1, 7),(-8, 2),(0, 0),(6, 6)}, then the range of G is

{(7, -1),(2, -8),(0, 0),(6, 6)}

{-8, -1, 0, 6}

{0, 2, 6, 7}


Given B = {a, l, g, e, b, r} and C = {m, y, t, h}, find B ∪ C.

{}

{a}

{a, b, e, g, h, l, m, r, t, y}


If A ⊂ B and A ∩ B = θ then which of the following can be concluded about the sets A and B?

Set A has more elements in it than set B.

Set A is the set containing zero.

Set A is the empty set.

Both sets A and B are the empty set.


Given A = {a, e, i, o, u} and B = {a, l, g, e, b, r}, find A ∪ B.

{}

{a,e}

{a, b, e, g, i, l, o, r, u}


Which of the following properties is 5(3 + 2) = 15 + 10 an example of?

associative property

commutative property

multiplicative identity

distributive property


Given f(x) = 3x - 1 and g(x)= -x + 6, find f(-2) + g(5).

-6

6

8


List all of the elements of set A if A = {x|x is an integer and -6 ≤ x <0}

{-6, -5, -4, -3, -2, -1, 0}

{-6, -5, -4, -3, -2, -1}

{-5, -4, -3, -2, -1}

Verified Answer :

  1. (-1,4)(1,4)(-2,4)(2,4) is a function because it has no repeating x values.

    2. A is a subset of B because everything in A is in B ?? not sure exactly what u r looking for 

    3. a(bc) = (ab)c.....associative property

    4. the intersection of A and C is { empty set } because they have no letters in common

    5. range is all ur y values....so the range of G is { 0,2,6,7 }

    6. the union of B and C is { a,b,e,g,i,l,o,r,u }

    7. set A is an empty set

    8. the union of A and B is { a,b,e,g,i,l,o r,u }

    9. 5(3 + 2) = 15 + 10....distributive property

    10. f(x) = 3x - 1.......f(-2) = 3(-2) - 1 = -6 - 1 = -7
          g(x) = -x + 6.....g(5) = -5 + 6 = 1
          f(-2) + g(5) = -7 + 1 = -6 <==

    11. { -6,-5,-4,-3,-2,-1 }
