How to write a function rile

this what i have

Step-by-step explanation:

A function rule such as cost = p + 0.08p is an equation that describes a functional relationship.

If p is the price you pay for an item and 0.08 is the sales tax, the function rule above is the cost of the item.

If you are given a table, usually you have to carefully examine the table to see what the function rule is.

Sometimes, it is easy to get the rule. Other times, it is not so easy. It may require some keen observation or using the concept of slope.

final answer is : )

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
