  1. What is the domain of the following relation? (use correct notation) • { (1, 3), (4, 5.5), (6, 9), (10, 0) }

  2. What is the domain of the following relation? (use correct notation) • { (1, 3), (4, 5.5), (6, 9), (10, 0) } • Answer: {1, 4, 6, 10}

  3. What is the range of the following relation? (use correct notation) • { (1, 3), (4, 5.5), (6, 9), (10, 0) }

  4. What is the range of the following relation? (use correct notation) • { (1, 3), (4, 5.5), (6, 9), (10, 0) } • Answer: {0, 3, 5.5, 9}

  5. Is the relation a function? Why or why not? • { (1, 3), (4, 5.5), (6, 9), (10, 0) }

  6. Is the relation a function? Why or why not? • { (1, 3), (4, 5.5), (6, 9), (10, 0) } • Yes- each x-value is paired with exactly one y-value

  7. Given the function g(x) = x2+6, evaluate g(-2).

  8. Given the function g(x) = x2+6, evaluate g(-2). • g(-2)=(-2)2 +6 = 4+6 = 10

  9. Given the function h(x) = x+6, evaluate h(a+4).

  10. Given the function h(x) = x+6, evaluate h(a+4). • h(a+4) = a+4+6 = a+10
