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.

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

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