Question

Bacteria is growing in a petri dish. initially, there were 10 bacteria in the dish and they are tripling every 3 minutes. what is an appropriate domain to for the function?

Answer 1

Domain of a function is the type of parameters it takes as input. The domain of a sine function is angle in either degrees or radians. The function that represents the population growth of the bacteria that is tripling every minute is given by the mathematical expression,

`x_(t) = x_(0) * 3^(t)`,

where, t is time in minutes,
`x_(0)` is the initial population size, and
`x_(t)` is the population at time, t.

The domain of this function will be time, t.
