4. A biologist studied the populations of common guppies and Endlers guppies over a 6 year period The biologist modeled the populations, in thousands, with the following polynomials where x is time, in years.
Common guppies 3.1X^2 + 6x +0.3
Endless guppies 4.2x^2-5.2x+1
What polynomial models the total number of common and endlers guppies
?
The polynomial that models the total number of common and endlers guppies would be the sum of the two individual polynomial models:
Total guppies = (3.1x^2 + 6x + 0.3) + (4.2x^2 - 5.2x + 1)
Total guppies = 7.3x^2 + 0.8x + 1.3
