Exploring Domain and Range in Word Problems

The video tutorial covers the concepts of domain and range in word problems, focusing on distinguishing between discrete and continuous data. It provides definitions and examples to illustrate these concepts, including scenarios involving selling CDs, working a summer job, and wrapping presents. The tutorial explains how to determine the domain and range for each example, using appropriate notation for discrete and continuous data.

What does the domain in a function typically represent?

• The set of possible input values

• The continuous data points

• The set of possible output values

• The discrete data points

What type of data can only include whole numbers?

• Continuous data

• Measured data

• Decimal data

• Discrete data

In the context of functions, how is discrete data typically represented?

• Decimal notation

• Graphical representation

• Set notation

• Inequality notation

What type of notation is used to represent the domain and range of continuous data?

• Inequality notation

• Set notation

• Fractional notation

• Percentage notation

If a function's data type allows for decimal values, what type of data is it?

• Continuous data

• Non-numeric data

• Integer data

• Discrete data

What is the domain of a function that models the number of hours worked per week, ranging from 15 to 35 hours?

• 15 to 35

• 0 to 35

• 10 to 35

• 15 to 40

For a function where the domain is the number of hours worked, and it includes partial hours, what type of data is this?

• Discrete data

• Continuous data

• Whole number data

• Static data

In a scenario where a club can wrap exactly 1000 presents, what is the highest value in the domain?

• 1000

• 999

• 100

• 1001

What notation is used to express the range of a function dealing with discrete data?

• Percentage notation

• Set notation

• Decimal notation

• Inequality notation

If a function describes the amount of money earned for wrapping presents, and the function is f(x) = 3x, what is the value of f(1)?

• 2

• 1

• 3

• 0
