# Which type of function should be used to model bacterial growth?

Jul 2, 2018

$\textcolor{b l u e}{\text{exponential}}$

#### Explanation:

You need a function in the form:

$A \left(t\right) = A \left(0\right) {e}^{k t}$

Where:

$A \left(0\right)$ is the amount present at the start .i.e. $t = 0$

$A \left(t\right)$ is the amount present after time $t$

$\boldsymbol{k}$ is the growth/decay factor.

$\boldsymbol{t}$ is the time.

$\boldsymbol{e}$ is Euler's number.
