Question 1202248
<font color=black size=3>
This is an <font color="red">exponential</font> function because the number of cells quadruple each hour. We multiply the previous cell count by 4 to get the new cell count.


1 cell -> 4 cells -> 16 cells -> 64 cells -> etc


A visual representation could be a tree diagram such as this example
*[illustration Screenshot_173.png]
Generation A = 1 cell
Generation B = 4 cells
Generation C = 16 cells
And so on.


The equation would be
y = 1*4^x
or simply
y = 4^x
where,
x = number of hours
y = number of cells


Example: if x = 2 hours elapse then y = 4^x = 4^2 = 16 cells are present (see generation C in the diagram above)
