If there are 81 gold coins with one of them a fake lighter coin, describe a non-adaptive solu- tion that will find the fake coin using 4 weighings of a pan balance. (hint: how many four letter words can be made using only the letters a, b and c? use these words to label the coins.) non-adaptive solution

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
