1. What is the general form of an exponential growth model?
Y= A*𝐵
𝑡
Where:
i) A >0 and B> 0
ii) B is greater than 1
Are all exponential models linear?
No. exponential model increase or decrease by an exponent. In contrast, linear models increase
or decrease by a constant value or number
2. What is in the general form for a linear model?
Y=mx+c
Where: m is the gradient and “c” is a constant term
3. What is in the exponential model?
Y= A*𝐵
𝑡
Where:
Y represents the decay or growth value at time, t
A represents the initial value
B is the rate of decay or growth takes all positive values with exception of 1.
4. When is the association negative in an exponential growth model?
When the value of B is less than 1 but greater the zero (0<B<1)
5. What do exponential models predict?
Exponential models predict phenomena or things growing or decaying non-linearly. In such
scenario, the growth rate or the decay rate increases or decreases faster with time
