Manoj and tamar are arguing about how a number trick they heard goes. tamar tells their friend andrew to think of a number, multiply it by five, and subtract three from the result. then manoj tells andrew to think of a number, add five, and multiply the result by three. andrew says that whichever way he does the trick he gets the same answer. what was andrew's number? justify your answer.

(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.
