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.
