Question

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

Answer 1

f(x) = 10 + 2x

Explanation:

The y-intercept (when there are no toppings, or when x is 0) is 10. Every topping after that is $2 extra, so 2x

Assemble the function and you get f(x) = 10 + 2x
