  1. Lesson 56Finite & Infinite Sets-Membership in a Set- Rearranging Before Graphing Finite – Limited or bounded {6, 7, 8, 9, 10} Infinite – Unlimited or unbounded {1, 2, 3, 4…} Membership in a Set If we have the numbers 0,0,0,0,0,0,1,1,1,1,2,2,2,2 and wish to designate set B we would write B = {0, 1, 2}

  2. Examples: Ex 56.1 Represent the following numbers as being member of set K. 1,0,2,1,0,5,7,4,5,7 K = {0, 1, 2, 4, 5, 7} Ex 56.2 Represent the following numbers as being member of set L. 7,15,0,1,15,0,8,-13 L = {-13, 0, 1, 7, 8, 15}

  3. Examples cont. Ex 56.3 Given the sets A = {0, 1, 3, 5}, B = {0, 4, 6, 7} & C = {1, 2, 3, 5, 7}, are the following statements true or false? a) 5 € A b) 4 € C c) 5 € B Ex 56.4 Given the sets L = {0, 1, 2, 3}, M = {5, 6, 7} & N = {0, 1}, are the following statements true or false? a) 6 € L b) 0 € N

  4. Rearranging Before Graphing Ex 56.5 Graph: 3x + 2y = 4 Subtract 3x: -3x -3x The result is: 2y = -3x + 4 Divide by 2: 2 2 2 The result is: y = -3/2x + 2 Ex 56.6 Graph: y – x = 0 Add x: +x +x The result is: y = x On Line Practice
