Question

the growth of bacteria in a dish is modeled by the function f(t)=t/2^3. for which value of t is f(t)=32

Answer 1

f(32)=(32)×2^3
2^3=8
32÷8=4
f(t)=4

Answer 2

The growth of bacteria is modeled by :

$f(t)=\frac{t}{2^{3} }$

Now we are to find value of t when f(t) is 32,

So plugging f(t) as 32 in the formula , let us find value of t,

$32=\frac{t}{2^{3} }$

t=256

Answer: At t=256, f(t) is 32
