The table shows the cost of pizza based on the number of toppings .write a function to find the cost for pizza with x toppings

Step-by-step explanation:

The given tables shows a relation that can be transform into a function.

From the table we deduct that each toppings cost $2, because for 1 topping is $12, for 2 is $14, for 3 is $16, and so on. So, the ratio of change is

Where represents the cost and represents the number of toppings.

Now, we use one pair from the graph (1,12), the ratio of change and the point-slope formula to find the function

Therefore, the function that expresses the given situation is

Where
