Question

The function f(t)=1900(1. 4)^t

t

represents the change in a quantity over t hours. What does the constant 1. 4 reveal about the rate of change of the quantity?

Answer 1

Increasing by 40%

Explanation:

This is a exponentional function. The format for this type of function is a(b)^x. So "a" is your initial value, and "b" is the rate. Now let's think to ourselves what times what is still equal to the same thing? That is 1. But in our question, we have 1.4. So we are increasing by 0.4, or 40%.
