Match the function with its value.

Step-by-step explanation:

1. asks you to add the two functions and , which would be

Simplify the like-terms and you get:

------------------

2. asks you to multiply the two functions and , which would be

In order to multiply the functions we use the FOIL method (for polynomials):

Multiply each term and you get:

Simplify the like-terms and you get:

------------------

3. asks for your ability to understand what composite functions are. In order to solve this, we will follow some careful steps and solve them separately.

Now that we have both values, we can just subtract them:

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
