In this lesson, we fill in a table with x and y values given a function rule with two-step rules. Usually the function rule is a linear equation in x and y. By giving different values to the independent variable x, corresponding values of dependent variable y are found. These x and y values are then put in a table. Thus a function rule with two-step rules is used to fill in a table with x and y values.

Fill in the table using this function rule.

y = 5x − 3

**Step 1:**

In y = 5x − 3, for x = 0, y = 5(0) − 3 = −3; for x = 1, y = 5(1) − 3 = 2;

Similarly, for x = 2, y = 7; for x = 3, y = 12 and for x = 4, y = 17.

**Step 2:**

Making a table of x and y values we get

Input(x) | Output(y) |
---|---|

0 | -3 |

1 | 2 |

2 | 7 |

3 | 12 |

4 | 17 |

Fill in the table using this function rule.

y = 3x − 3

**Step 1:**

In y = 3x − 3, for x = 0, y = 3(0) − 3 = −3; for x = 1, y = 3(1) − 3 = 0;

Similarly, for x = 2, y = 3; for x = 3, y = 6 and for x = 4, y = 9.

**Step 2:**

Making a table of x and y values we get

Input(x) | Output(y) |
---|---|

0 | -3 |

1 | 0 |

2 | 3 |

3 | 6 |

4 | 9 |
