1) which of the following sets represents the domain of the function shown?
((2,,,-,18))
a) (-4, 2, 7, 13, 15, 18, 21, 24)
b) ((724)
c) (2,15,21,24)
d) (-4,7,13,18)
2) the table shows the outputs y for different inputs x:
input(x): 3,7,11,15
output(y): 4,7,8,10
part a) do the data in this table represent a function? justify your answer.
part b) compare the data in the table with the relation f(x)=5x-21. which relation has a greater value when x=11?
part c) using the relation in part b, what is the value of x if f(x)=99?

Here is their argument. given the obtuse angle x, we make a quadrilateral abcd with ∠dab = x, and ∠abc = 90◦, and ad = bc. say the perpendicular bisector to dc meets the perpendicular bisector to ab at p. then pa = pb and pc = pd. so the triangles pad and pbc have equal sides and are congruent. thus ∠pad = ∠pbc. but pab is isosceles, hence ∠pab = ∠pba. subtracting, gives x = ∠pad−∠pab = ∠pbc −∠pba = 90◦. this is a preposterous conclusion – just where is the mistake in the "proof" and why does the argument break down there?
