It gives us another layer of insight for predicting future events. We learn a lot about things by seeing their visual representations, and that is exactly why graphing exponential equations is a powerful tool. Most of the time, however, the equation itself is not enough. Working with an equation that describes a real-world situation gives us a method for making predictions. Write the equation of an exponential function that has been transformed.Īs we discussed in the previous section, exponential functions are used for many real-world applications such as finance, forensics, computer science, and most of the life sciences.Graph a reflected exponential function.On the other hand, all graphs of power functions with odd exponent are. Graph a stretched or compressed exponential function. The HHI is calculated by taking the market share of each firm in the industry, squaring them, and summing the result, as depicted in the equation above. The powers are all even, therefore the power functions are axis symmetric to the y-axis.

If you'd like to know how to estimate compound interest, see the article on The process of finding the equation that suits best for a set of data is called as exponential regression. (or the advanced formula with annual additions),Īs well as a calculator for periodic and continuous compounding. See How Finance Works for the compound interest formula, Graph a stretched or compressed exponential function. It also accounts for the effects of inflation,Īnd the importance of paying down your debt. Graph exponential functions shifted horizontally or vertically and write the associated equation. How To: Given two points on the curve of an exponential function, use a graphing calculator to find the equation. It is the basis of everything from a personal savings plan to the long term growth of the stock market. The same rules apply when transforming logarithmic and exponential functions. To find an exponential function, f(x)ax f ( x ) a x, containing the point, set f(x) f ( x ) in the function to the y y value 25 25 of the point, and set x x.
Compound interest - meaning that the interest you earn each year is added to your principal, so that the balance doesn't merely grow, it grows at an increasing rate - is one of the most useful concepts in finance.
