Key Concepts

Constant Percentage Growth

A constant percentage growth means that the function’s rate of increase is proportional to its current value, resulting in the same percentage increase for each unit increase in the independent variable. This is a hallmark of exponential functions, where multiplying by a constant factor (greater than 1 for growth) achieves this effect.

Vertical Intercept

The vertical intercept is the value of the function when the independent variable is zero. In the context of creating functions that model real-world phenomena, ensuring that the exponential function has the same vertical intercept as a given function means setting the initial value (the coefficient a in f(x) = a · b^x) to that intercept value.

Exponential Function

An exponential function is one in which the variable appears as an exponent. It is typically expressed in the form f(x) = a · b^x, where a is the initial value (or vertical intercept when x = 0) and b is the base that determines the growth or decay rate.
