A population of amoebas in a petri dish will triple in size every 20 minutes. At the start of an experiment the population is 800. Write a function to model this relationship with y representing the total population, and x as the number of 20 minute periods.

y=800(3)xy=800\left(3\right)^x

y=3(800)xy=3\left(800\right)^x

y=800(20)xy=800\left(20\right)^x

y=20(3)xy=20\left(3\right)^x
