Question

What is a rule that represents the function, (0,1), (1,3), (2,9), (3,27), (4, 81)?

Answer 1

Answer:

x = -21/5

Step-by-step explanation:

Notice that each new y- value is 3 times the previous y-value.  Thus, the function is y = 3^(n-1).

Check:  If n = 1, y = 3^0 = 1.  This is correct.

             if n = 3, y = 3^2 = 9.  This is correct.

Answer 2
