Goodday Grade 9
Today we continue with the topic: Functions and Relationships. We are looking at Describing relationships in tables.
We use rules or formulae to describe the relationships between the numbers in the top row and the numbers in the bottom row of the tables.
Refer to Exercise 15.3 in your study pack or refer to page 169 in Platinum…[Read more]
Goodday Grade 8 Class
We are still on the topic Functions and Relationships. Today we shall be looking at Use of tables to determine output values.
Rules are used to determine the output on the table. Inorder to come up with the rule, you need to determine the constant difference and determine the rule from there.
Study the attached example…[Read more]
