Choose the graph of the following function: f (x) = negative 2 cosine (0.5 x)
Graph A
On a coordinate plane, a function curves down through (0, 0) to (3, negative 2), curves up through (6, 0) to (9, 2), and curves down through (12, 0).
Graph B
On a coordinate plane, a function has a minimum at (0, negative 2) and increases through (3, 0) to (6, 2), and then decreases through (9, 0).
Graph C
On a coordinate plane, a function has a minimum at (0, negative 2) and increases through (0.5, 0) to (1.5, 2), then decreases through (2.5, 0) to (3, negative 2).
Graph D
On a coordinate plane, a function increases through (0, 0) to (0.5, 2) and decreases through (1.5, 0) to (2.5, negative 2).

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."

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
