Question

The function f(x) = 1(3)* models the number of virus cells present in asample after x minutes. About how many cells will be present after 1 1/2minutes?

Answer 1

Given data:

The given expression is f(x)= 1(3)^x.

Substitute 1 1/2 for x in the given expression.

`\begin{gathered} f(1(1)/(2))=1(3)^{(1(1)/(2))} \\ =1(3)^{(3)/(2)} \\ =5.196 \\ \approx5 \end{gathered}`

Thus, after 1 1/2 min number of cells are 5.
