Question

A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled y with entries 4.5, 6.75, 10.125, 15.1875.
What is the multiplicative rate of change of the exponential function represented in the table?

1.5
2.25
3.0
4.5

Answer 1

1.5

Each successive y is multiplied by 6.75/4.5 = 10.125/6.75 = 15.1875/10.125 = 1.5.
