Answer:

Step-by-step explanation:

f(x) + g(x)

= $\frac{x}{2}$ - 3 + 3x² + x - 6 ← collect like terms

= 3x² + $\frac{3}{2}$ x - 9 → D

<span>B) (1, 5) is your best answer

B (0,6) creates the top of the kite
D (0,2) creates the bottom
A (-1,5) creates the left side of the kite
D (1,5) creates the right side (only the x is flipped, because has congruent sides of both the top, and both the bottom.
