Question

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.
common guppies: 3.1x^2 + 6x + 0.3
Endler’s guppies: 4.2x^2 – 5.2x + 1
What polynomial models the total number of common and Endler’s guppies? (1 point)

Answer 1

7.3x^2+0.8x+1.3


I think that's the answer.

Answer 2
