What are the domain and range of f(x) = 4x – 8? a. domain: {x | x is a real number}; range: {y | y > –8} b. domain: {x | x is a real number}; range: {y | y > 8} c. domain: {x | x > 4}; range: {y | y > –8} d. domain: {x | x > –4}; range: {y | y > 8}

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."

What value of x is in the solution set of 4x - 12 s 16 + 8x? -10 -9 -8 -7
