You are going to model the population size of a species of bird that is gradually becoming extinct. Which graph is the BEST choi

kvasek [131]

Hey Jay,
Since we can't see the graphs, we can't be entirely sure, but given that we are trying to model the population size of a species of bird that is slowly going extinct. I would say the best graph would be a line graph. Line graphs show changes over time so this would be the best graph to use. Hope this helped!

Cheers,
Izzy
