Mathematical Process Standards>Creating and Using Representations to Organize and Record Math Ideas(TEKS.2A.9-12.1.E) Practice Test

A lab recorded population $P$ of bacteria each hour $t$ for 12 hours, and $P$ appears to grow by about the same factor each hour. Which representation best supports selecting an exponential model and making a prediction for $P$ at $t=10$?

A lab records population $P$ of a culture at times $t$ (hours): $t=0,3,6,9,12$, and $P$ roughly doubles every 3 hours. You want to choose a model and predict $P$ at $t=15$. Which representation best supports selecting a model and making predictions?
