Mr. macho, my great dane, ate 125 hot dogs over a five day period. each day he ate seven more hotdogs than on the previous day. how many hot dogs did he eat on the first day?

tell me how to do it

(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.
