Question

Given the exponential decay equation y = 4(0.8)^x what is the initial value?

Answer 1

I think it is 4.8 because

Answer 2

The initial value of the exponential decay equation y = 4(0.8)ˣ is 4

How to determine the initial value of the exponential decay equation

From the question, we have the following parameters that can be used in our computation:

y = 4(0.8)ˣ

To determine the initial value of the exponential decay equation, we set x = 0

So, we have

y = 4(0.8)⁰

This gives

y = 4 * 1

Evaluate

y = 4

Hence, the initial value of the exponential decay equation is 4
