Question 1

Given matrices: A = [ 3 4] [ 2 4] B = [ 1 3] [ 1 2] Compute: A × B
Matrix multiplication:
A × B =

[ 7 17]
[ 6 14]

Question 2

If '≺' means '<', then determine: 17 ≺ 5
≺ = <
17 < 5 is False

Question 3

If k(x) = x + 2x, then find k(9)
Substituting x = 9:
9 + 29 = 38

Question 4

If f(x)=x+2, g(x)=2x, h(x)=x², p(x)=x-3, q(x)=x/2, r(x)=3x-1, then evaluate: p(r(3))
Evaluate from innermost outward:
p(r(3))
= 29

Question 5

If '≽' means '≥', then determine: 13 ≽ 16
≽ = ≥
13 ≥ 16 is False

Question 6

If ∆ = +, ♢ = + (standard order of operations applies), then evaluate: 4 ∆ 11 ♢ 10
Substituting symbols: 4 + 11 + 10
Applying order of operations: = 25

Question 7

Given matrices: A = [ 3 5] [ 2 1] B = [ 3 4] [ 1 4] Compute: A - B
Matrix subtraction:
A - B =

[ 0 1]
[ 1 -3]

Question 8

Given: A = {4, 6, 7, 8, 9} B = {1, 3, 6, 7, 8, 9} C = {1, 2, 3, 7, 8, 9} Find: B △ A
Symmetric Difference of B and A:
{1, 3, 6, 7, 8, 9} △ {4, 6, 7, 8, 9} = {1, 3, 4}

Question 9

If f(x)=x+2, g(x)=2x, h(x)=x², p(x)=x-3, q(x)=x/2, r(x)=3x-1, then evaluate: q(r(6))
Evaluate from innermost outward:
q(r(6))
= 17.50

Question 10

If k(x) = x + 2x, then find k(1)
Substituting x = 1:
1 + 21 = 22

Question 11

Given: A = {2, 5, 6, 8, 9, 10} B = {3, 8, 10} C = {2, 5, 7, 8} Find: C ∪ B
Union of C and B:
{2, 5, 7, 8} ∪ {3, 8, 10} = {2, 3, 5, 7, 8, 10}

Question 12

Given matrices: A = [ 5 3] [ 2 1] B = [ 1 1] [ 5 2] Compute: A - B
Matrix subtraction:
A - B =

[ 4 2]
[-3 -1]

Question 13

If f(x) = x + 3, then find f(7)
Substituting x = 7:
7 + 3 = 10

Question 14

Given: A = {3, 4, 6, 9} B = {3, 4, 5, 6, 9, 10} C = {1, 2, 3, 4, 7} Find: A ∩ B
Intersection of A and B:
{3, 4, 6, 9} ∩ {3, 4, 5, 6, 9, 10} = {3, 4, 6, 9}

Question 15

In the notation system where ☆ means x², what is the value of ☆(7)?
Applying ☆ to 7:
7² = 49

Question 16

If h(x) = x³/2, then find h(1)
Substituting x = 1:
1³/2 = 0.50

Question 17

Given matrices: A = [ 5 1] [ 1 3] B = [ 3 5] [ 3 2] Compute: A + B
Matrix addition:
A + B =

[ 8 6]
[ 4 5]

Question 18

If '≺' means '<', then determine: 12 ≺ 7
≺ = <
12 < 7 is False

Question 19

If ◊ = ×, ⊗ = × (standard order of operations applies), then evaluate: 13 ◊ 3 ⊗ 8
Substituting symbols: 13 × 3 × 8
Applying order of operations: = 312
