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)=

1 day: 4480

2 days: 8960

3 days: 13440

---- function inverse

Step-by-step explanation:

Given

Solving (a): The amount present after 1 day.

Here,

So:

Solving (b): The amount present after 2 days.

Here,

So:

Solving (c): The amount present after 3 days.

Here,

So:

Solving (d): The inverse function of:

Replace f(x) with y

Swap x and y

Rewrite as:

Divide by 4

Take square roots

Replace y with function inverse

the answer is. -82562234434584
