Abaking recipe makes 30 brownies requires 1 1/4 scoops of sugar. when the ingredients in this recipe or increased proportionally, how many scoops are required for the recipe to make 120 brownies?

(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.
