Key Concepts

Function Evaluation

Function evaluation involves substituting specific values into a function to determine the corresponding output. In the context of exponential models, evaluating the function at particular time points allows one to compute the quantity of interest at those moments.

Growth Factor

The growth factor is the constant by which the initial amount is multiplied for each time unit elapsed. In exponential growth models, this factor determines how quickly the quantity increases and is integral to calculating future values.

Initial Value

The initial value in an exponential function is the quantity present at time t = 0. It serves as the starting point for understanding how much the quantity will be affected by the exponential growth as time progresses.

Exponential Growth

Exponential growth is a process in which a quantity increases by a constant factor over equal increments of time. This is typically modeled using functions of the form N(t) = N? * b?, where N? represents the initial amount and b is the growth factor, leading to rapid increases as t increases.
