A biologist studied the populations of common guppies and Endler’s guppies over a 6-year period. The biologist modeled the populations, in tens of thousands, with the following polynomials where x is time, in years.

Question

common guppies: 3.1x2 + 6x + 0.3
Endler’s guppies: 4.2x2 – 5.2x + 1
What polynomial models the total number of common and Endler’s guppies?

Answer 1

just add them up:

3.1x^2+6x+0.3
4.2x2-5.2x+1
----------------------
7.3x^2+0.8x+1.3

Answer 14

Let me tell you all this 📢. Don't just write answers! When you write the answers make sure you write from what state your from cuz every state has different answering techniques. So If you have answers write the answers and write wherever you want as long as we can see it write the state name!! 👏
