The number of users on a website is 630 and is growing exponentially at a rate of 76% per year. Write a function to represent th
Dafna1 [17]

The exponential function that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

The daily rate of change is of 20.82%.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

For this problem, the parameters are given as follows:

A(0) = 630, r = 0.76

Hence the equation that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

An year has 365 days, hence the rate of change per day is given by:

76/365 = 0.2082 = 20.82%.

The daily rate of change is of 20.82%.
