Question

Y = 100 (1.25)^t

Is this function a growth or decay?
What is the growth or decay rate for this function? Write it as a percentage.
%

Answer 1

The function y = 100 (1.25)^t represents exponential growth with a growth rate of 25%.

Step-by-step explanation:

The function y = 100 (1.25)^t represents exponential growth because the base, 1.25, is greater than 1. In this function, as t (time) increases, y (the value) also increases.

The growth rate for this function can be found by subtracting 1 from the base and then multiplying by 100 to express it as a percentage.

In this case, the growth rate is (1.25 - 1) * 100 = 25%.
