Additive and Multiplicative Relationships

Front

What is an additive relationship?

Back

An additive relationship is when one quantity increases or decreases by a constant amount, resulting in a linear relationship. For example, if you add 2 apples every day, the total number of apples is an additive relationship.

What is a multiplicative relationship?

Back

A multiplicative relationship is when one quantity is multiplied by a constant factor, resulting in an exponential growth or decay. For example, if you double the number of cookies every hour, the total number of cookies is a multiplicative relationship.

How can you represent an additive relationship in a table?

Back

In a table, an additive relationship shows a constant difference between consecutive values. For example, if you start with 5 and add 3 each time, the table would show: 5, 8, 11, 14.

What is the equation for a multiplicative relationship?

Back

The equation for a multiplicative relationship can be written as y = a * b^x, where a is the starting value, b is the constant factor, and x is the number of times the factor is applied.

How do you identify a multiplicative relationship from a graph?

Back

A multiplicative relationship on a graph shows a curve that increases or decreases exponentially, rather than a straight line.

What is a real-world example of an additive relationship?

Back

A real-world example of an additive relationship is saving money. If you save $10 every week, your total savings increases by $10 each week.
