What is an example of a real world scenario that is a function that has a domain and range?

Domain and Range In this function, the number of gallons used can be anywhere from 0 gallons to 20 gallons, since the tank holds 20 gallons of gas. Based on this and the fact that the car gets 32 miles per gallon, Zack can drive anywhere from 0*32 = 0 miles to 20*32 = 640 miles on one tank of gas.

Which is an example of a function?

The formula for the area of a circle is an example of a polynomial function. The graph of the function then consists of the points with coordinates (x, y) where y = f(x). For example, the graph of the cubic equation f(x) = x3 − 3x + 2 is shown in the figure.

How can you apply the concept of one to one functions in your daily life?

One person has one passport, and the passport can only be used by one person. One person has one ID number, and the ID number is unique to one person. A person owns one dog, and the dog is owned by one person. In monogamous relationships, one person has one partner, who is only partnered with that person.

What are some other real-world examples where a piecewise function might be used?

Tax brackets are another real-world example of piecewise functions. For example, consider a simple tax system in which incomes up to $10,000 are taxed at 10 , and any additional income is taxed at 20\% .

What are real life situations?

The real-life situation should be concrete and easily identifiable. It cannot be a broad topic (euthanasia, vegetarianism) but a specific event, experience or contemporary issue. They can be taken from your own experiences, interests or other subjects that you study.

What is a real life example of range?

Using Range In Real Life Range is used in real life to make mathematical calculations. Range can be used to calculate the amount of time that has passed, like when calculating your age. The current year is 2020 , and you were born in 2005 .

What are the uses of functions?

Why we need functions in C a) To improve the readability of code. b) Improves the reusability of the code, same function can be used in any program rather than writing the same code from scratch. c) Debugging of the code would be easier if you use functions, as errors are easy to be traced.

What are four examples of functions?

we could define a function where the domain X is again the set of people but the codomain is a set of number. For example , let the codomain Y be the set of whole numbers and define the function c so that for any person x , the function output c(x) is the number of children of the person x.

What is an everyday example of a one to many relationship?

Here are some other examples of one-to-many relationships: People-Addresses (Each person can live at one address, but each address can house one or more people.) Owners-Pets (Each pet has one owner, but each owner can have one or more pets.)

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 .
