Biologist studied the population of common Guppies and Inland Guppies over 6-year period the biologist modeled the patterns and tens of thousands with the following polynomials where X is time in years what polynomial models the total number of common and endler Guppies

The polynomial that could potentially model the total number of common and endler Guppies over a 6-year period could be something like the following:

f(x) = ax^2 + bx + c

This is a simple quadratic polynomial where the coefficients a, b, and c would need to be determined based on the data collected by the biologist over the 6-year period. The biologist would need to perform regression analysis using the data collected to determine the best-fit values for a, b, and c that accurately represent the population growth trend of the Guppies over time.
