Suppose it takes 4 hours for a certain strain of bacteria to reproduce by dividing in half. If 70 bacteria are present to begin
with, the total number present after xxdays is f(x)=70⋅64x
Find the total number present after 1, 2 and 3 days.
There will be bacteria present after 1day, after 2 days and after 3 days.
____________
secondly,
Find f−1for the function ff.
f(x)=4x2+4
f−1(x)=
