- Human Population.
- Compound Interest.

What are the examples of exponential equation?
An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable. For example, 3x = 81, 5x – 3 = 625, 62y – 7 = 121, etc are some examples of exponential equations.
What is a real life example of a linear function?
Linear modeling can include population change, telephone call charges, the cost of renting a bike, weight management, or fundraising. A linear model includes the rate of change (m) and the initial amount, the y-intercept b .
What is an example of an exponential growth function?
An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours. This can be written as f(x) = 2x.
How do exponential functions apply and transform in real life?
Exponential functions are functions that model a very rapid growth or a very rapid decay of something. They are used to calculate finances, bacteria populations, the amount of chemical substance and much more. In the exponential function the input is in the exponent.
Is half life an example of an exponential decay?
Half-Life. We now turn to exponential decay. One of the common terms associated with exponential decay, as stated above, is half-life, the length of time it takes an exponentially decaying quantity to decrease to half its original amount.
What are examples of linear functions?
A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x – 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x – 2.
How do you write an exponential function?
If neither of the data points have the form (0,a) , substitute both points into two equations with the form f(x)=abx f ( x ) = a b x . Solve the resulting system of two equations to find a and b. Write the exponential function, f(x)=abx f ( x ) = a b x .
What is a real world example of exponential decay?
Radiocarbon Dating The process of radiocarbon dating highly depends on the radioactive decay of the isotopes of radioactive elements, hence forms a prominent example of exponential decay in real life. Radiocarbon dating also helps the researchers to estimate the time when an ancient artefact was built.
What are real life examples of functions?
– The amount of sodas that come out of a vending machine depending how much money you insert. – The amount of carbon left in a fossil after so many years. – The velocity of an object in freefall after being
What are real life examples absolute value function?
Absolute Value Functions Real World Applications As you know Absolute Value is a way to eliminate negative numbers in situations in which they are not called for. For example, if your student walks to school and it is a 2 mile walk we would say he or she walked 2 miles.
What are the applications of functions in real life?
– Money won after buying a lotto locket – The high temperature on July 1st in New York City. Depends on the year. – How many words your spouse uses when answering, “How are you?” – The number of calories in a fast food hamburger – Places you can drive to with 1 gallon left in your gas tank
How do exponents apply to real life situations?
COMPUTERS: -Exponents are often used to describe a computer’s memory. For example: 1gigabyte of RAM means that you have 1 x 10 bytes.
