A medium 1 topping pizza costs $12, and each additional topping costs $0.50. Don paid $16.50 for a medium pizza. If x gives the number of additional toppings Don ordered, which of the following equations describes the situation?

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the correct answer is $7.38
