Question

A scientist is studying a form of bacteria that doubles every hour. If the petri dish startswith 2 grams of bacteria, which image and equation best model the growth of thebacteria in the dish?

Answer 1

`\begin{gathered} Initial\text{ amount = 2} \\ y=2\cdot2^x \\ \text{Checking, in 6 hours there will be 128 grams} \\ y=2\cdot2^6 \\ y=2\cdot64 \\ y=128. \\ \text{The best equation is }y=2\cdot2^x \end{gathered}`
