Answer:
a = 5, b = -12
Step-by-step explanation:
By basic factoring, you get 9 - 12i + 
. Since 
is simply -1, the expression evaluates to 9 - 12i - 4, which is 5 - 12i.

Answer:
d. x-axis
Step-by-step explanation:
Consider a point on curve P and its (nearest) image on curve P'. The midpoint between those points is on the line of reflection. That line is the x-axis.
_____
<em>Additional comment</em>
The curve is symmetrical about the y-axis, so each point on P also has an image point that is its reflection across the origin. The reflection of P could be across both the x- and y-axes, or (equivalently) across the origin. We don't know the meaning of "xy-axis", so we suspect that is a red herring. The best choice here is "x-axis."
