Answer:
Let <em>i </em>be the input value, and let <em>o </em>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 ✔
