Question

Given the inputs in the table, which function rule produces the outputs?

Answer 1

Answer:

Let i be the input value, and let o be the output value.

o = i + (i + 3)

Step-by-step explanation:

Let's test each of the four numbers in the function rule.

3:

9 = 3 + (3 + 3) ?

9 = 3 + 6 ? 9 = 9 ✔

6:

15 = 6 + (6 + 3) ?

15 = 6 + 9? 15 = 15 ✔

9:

21 = 9 + (9 + 3) ?

21 = 9 + 12? 21 = 21 ✔

12:

27 = 12 + (12 + 3) ?

27 = 12 + 15? 27 = 27 ✔
