Question

Without graphing, determine whether the function represents exponential growth or exponential decay.

y = 129(1.63)x


exponential decay


exponential growth

Answer 1

Exponential growth.

Explanation:

The function represents exponential growth. This is because the rate of growth (1.63) is more than 1. If the rate were less than 1, the values would decrease, since it would be like multiplying a number by 0.5 many times.

Hope this helps!
