Bob wants to create two pens. one pen if for a garden and it needs a heavy duty fence to keep out the critters. this heavy duty fence costs $15 per foot. the dog pen shares a side with the garden and has a lighter weight fence on the other three sides that costs $5 per foot. if each pen is to have an area of 504, find the values of x and y that would minimize the total cost of the fencing.

(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.
