2.1 & 2.2: Output Values and Flow Diagram

Formula: y = 2x - 2

a) If x = 0.5: y = 2(0.5) - 2 = 1 - 2 = -1

b) If x = 1: y = 2(1) - 2 = 2 - 2 = 0

c) If x = 1.5: y = 2(1.5) - 2 = 3 - 2 = 1

d) If x = 2.5: y = 2(2.5) - 2 = 5 - 2 = 3

Flow Diagram:

|x |y |

|-----|-----|

| 0.5 | -1 |

|1 |0 |

| 1.5 | 1 |

| 2.5 | 3 |
