2. Problem #25
 In other words, the question is asking you to reflect the
point (2,9) firstly in the x-axis, and secondly in the y-axis.
 The point (2, -9) and the point (2, 9) are mirror images of
each other in the x-axis (they are symmetrical about [with
respect to] the x-axis)
 The point (-2,9) and the point (2,9) are mirror images of
each other in the y-axis.
 The reflection about the origin means to reflect over x-axis
AND then reflect over the y-axis reflection.
(2,9)  (2, -9)  (-2, -9)

9. Problem #31
Make it “y equals”
Switch the x and the y
Multiply by -7 on both sides
Square both sides
Subtract 16 on both sides
Multiply by -1 on both sides
Square root both sides

11. Problem #32
 Since this graph does not give you its function, you must
switch its “x” and “y” values
