FAQ

Q: What is a function?
A: A function is a relation between a set of inputs and a set of outputs, where each input has exactly one corresponding output.

Q: What is linear modeling?
A: Linear modeling is the process of creating a linear function that represents a real-world situation.

Q: What is the answer key?
A: The answer key is a document that provides the correct answers to the questions or problems in a worksheet.

Q: Why are functions important in mathematics?
A: Functions are important in mathematics because they allow us to describe and analyze relationships between variables.

Q: How do you represent a function?
A: A function can be represented using a graph, a table of values, an equation, or a verbal description.

Q: What is a linear function?
A: A linear function is a function whose graph is a straight line.

Q: What is the formula for a linear function?
A: The formula for a linear function is y = mx + b, where m represents the slope and b represents the y-intercept.

Q: What does the slope of a linear function represent?
A: The slope of a linear function represents the rate of change or the steepness of the line.

Q: What does the y-intercept of a linear function represent?
A: The y-intercept of a linear function represents the value of y when x is equal to zero.

Q: How do you determine the slope of a line?
A: To determine the slope of a line, you can use the formula (change in y)/(change in x) or calculate it using two points on the line.
