The function is of the form y = a(1 + r)t, where 1 + r > 1, so it represents exponential growth. Use the growth factor 1 + r to find the rate of growth. Write an equation.
Which exponential function represents growth?
There are two types of exponential functions: exponential growth and exponential decay. In the function f (x) = bx when b > 1, the function represents exponential growth.
How do you know if a function is exponential growth or decay?
If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay.
