Chapter 8: Exponential and Logarithmic Functions

Please post a response to the following questions:
1. What are some of the ways Exponential and Logarithmic Functions are used in the "Real World"? Please explain your answer in detail.

2. How does the properties of exponents we have learned in the last 2 chapters help us to solve exponential and logarithmic functions? Or do they have no bearing on the subject?

Please include only your first name and last initial in your responses.

1. One way that Exponential and Logarithmic Functions are used in the real world is in various investments. When making an investment at the bank for instance, you start off with a set amount in your account, but each year your amount can increase by 5 percent for example.

2. The properties of exponents have helped us solve exponential and logarithmic functions because logarithisms have exponents. With these exponents, you need to know what opperation to use. You can figure out which one to use by refering to the properties of exponents that we have learned in previous chapters.

1.they are used to figure out prices or investments..
(the yearly amount being taken out or being put in)
2.the properties of exponents helps us solve logarithisms by letting us know what degree the number is bein raised too.

1. one way that exponential and logarithmic is used is maybe in construction when they are measuring materials and the height of the building.

2.No bearing on the subject.Troy Hunter

1.Some ways that logarithmic functions are used in real life is by money investments and figuring out original prices when making purchases.
2.The properties of exponents help us to solve exponential and logarithmic functions by raising powers,condensing,and using the power propeties.Which allows us to evaluate the problems and simplify them as well.

1.I would have to say they are used in the medical field.
2.I exponents help us in many way especially in math and with our homework.

1. One way that exponential and logarithmic function are used in the real world is in various investments, when you are cou nting money or when you are checking your pay check.
2. The properties of exponent have help us with the exponents because they have exponents on it.

1.)They are used when paying your bills.

2.) letting us know what number it needs to be raised to.

Exponential and Logarithmic Functions are used in everyday life is dealing with investments.


Exponents have helped us solve logarithmic functions. Their are many operations to solving these problems. for more info. check out our recent chapter.

1) A way we use Exponential and Logarithmic Functions in the real world is in when one goes to the bank to start a saving accont.You get back compound inserst over a period of time.

2)The properties of exponents helped in many ways, how to solve exponential and logarithmic functions in that they tells what propeties to use or the number to raise to.
