Answer:
Domain
Step-by-step explanation:
As you notice, the more days that pass, the larger the plant grows.
Here's a rule that applies to this expression:
- Dividing exponents of the same base:
![\frac{x^m}{x^n}=x^{m-n}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5Em%7D%7Bx%5En%7D%3Dx%5E%7Bm-n%7D%20)
For this, just divide:
![\frac{3^{-9}}{3^{-12}}=3^{-9-(-12)}=3^3](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%5E%7B-9%7D%7D%7B3%5E%7B-12%7D%7D%3D3%5E%7B-9-%28-12%29%7D%3D3%5E3%20)
<u>Your answer is 3^3, or the third option.</u>
You can't draw a quadrilateral with two sets of parallel lines because parallel lines aren't supposed to touch each others, but you can draw them with no right angles, like a long rhombus, with two acute angles, and 2 obtuse angles.
