Answer:
C, D
Step-by-step explanation:
The equation for the x-coordinate will have the x-coordinate of the midpoint (-1/2) on the left side of an equation involving x2. Choice C applies.
The equation for the y-coordinate will have the y-coordinate of the midpoint (-1) on the left side of an equation involving y2. Choice D applies.

<em>Additional comment</em>
When you solve the equation
M = (P +Q)/2
for P, you find that ...
P = 2M -Q . . . . . . . . our favorite way to find the other end point
or ...
x2 = 2(-1/2) -3 = -4
y2 = 2(-1) -(-5) = 3
The coordinates of P are (-4, 3).

Explanation:
The piecewise function f(x) changes based on what the input is.
We have two cases:
- Case A) if x > 4, then f(x) = 3x-1
- Case B) If , then f(x) = 2x
The input x = -3 satisfies the inequality , so we go with case B for this input
f(x) = 2x
f(-3) = 2(-3)
f(-3) = -6
In contrast, the input x = 7 satisfies the inequality x > 4. So we go for case A this time.
f(x) = 3x-1
f(7) = 3(7)-1
f(7) = 21-1
f(7) = 20
----------------------
Side note: It might be better to let g(x) = 3x-1 and h(x) = 2x. Then we could further say "If x > 4, then f(x) = g(x) OR if , then f(x) = h(x)". Though this might be a more wordy definition.
