1) What is the slope of the line containing the midpoint of the segment with endpoints at (2,4) and (0,-2) and the midpoint of the segment with endpoints at (5,1) and (1,5) Express your answer in simplest form.
2) Suppose the graph of y = f(x) includes the points (1,5), (2,3) and (3,1).
Based only on this information, there are two points that must be on the graph of y = f(x(x)) . If we call those points (a,b) and (c,d) what is ab + cd?
+310 2) When you put 3 into f(x), you get 1. When you put 1 into f(x), you get 5. So one point in f(x(x)) is (3,5).
When you put 2 into f(x), you get 3. When you put 3 into f(x), you get 1. So the second point on f(x(x)) is (2,1).
3*5+2*1=17
