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: 3.2x^2+5x+0.2

Endler's guppies: 4.2x^2-5.1x+1

what polynomial models the total number of common and Endler's guppies

Answer 1

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: 3.1x2 + 6x + 0.3
