Question

The function f(t) = 7800(0.9925) ốo represents the change in a

quantity over t seconds. What does the constant 0.9925 reveal about
the rate of change of the quantity?

Answer 1

The rate of change of the function reduces

Explanation:

Given

`f(t) = 7800(0.9925)^t`

Required

What does 0.9925 imply

An exponential function is represented as:

`y = ab^x`

Where b is the rate of change

By comparison:

`b = 0.9925`

When b < 1, it implies that the rate of change of the function reduces

So:

The value 0.9925 implies that as t increases, f(t) reduces
