Is the function y = 1/x, shown in the graph below, invertible? If not, what is the restriction on the domain that will change it from non-invertible to invertible? a.) No, the function is not invertible. If the domain is restricted to x>1 or x<-1, then it will become invertible.
b.) No, the function is not invertible. If the domain is restricted to -1≤x≤1, then it will become invertible.
c.) Yes, the function is invertible.
d.) No, the function is not invertible. If the domain is restricted to x>0 or x<0, then it will become invertible.

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
