Finding an equation given a table of values using addition and multiplication

The video tutorial explains how to identify relationships in mathematical functions using x and y values. It covers methods to determine these relationships through addition, subtraction, multiplication, and division. The tutorial emphasizes the importance of unique x values in defining functions and provides examples to illustrate these concepts.

What is one way to represent a relationship between x and y values?

• Using a histogram

• By writing a story

• Through mapping

• Using a pie chart

When finding a relationship, what is the first method you should try?

• Multiplication

• Division

• Addition and subtraction

• Graphing

If f(x) = x + 2, what is f(0)?

• 6

• 4

• 0

• 2

What should you consider if addition and subtraction do not work for finding a relationship?

• Try using subtraction again

• Look for a different set of x values

• Use multiplication or division

• Change the y values

If y = -3x, what is y when x = -2?

• 3

• -6

• 6

• 0
