Question

8. Find the function rule.

x : -2 | -1 | 0 | 1 | 2 |
y : 9 | 4 | -1 | -6 | -11

Answer 1

Step-by-step explanation:

y = -5x - 1 should be your function.

Check. Plug in the x to get the desired y

9 = -5(-2) - 1

9 = 10 - 1

9 = 9 (correct)

4 = -5(-1) - 1

4 = 5 - 1

4 = 4 (correct)

-1 = -5(0) - 1

-1 = 0 - 1

-1 = -1 (correct)

etc.
