The table below shows the number of each item sold at the concession stand. What might the ratio of 5:4 represent? popcorn sold 20
nachos sold 15
hotdog sold 25
candy bar sold 30

The price of of the hotdog to the price of popcorn is in the ratio 5:4

25:20 is 5:4

(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.
