Answer:

in all cases x/100 is just a way to represent percentage. and since it's the same everywhere, it's not even relevant to decide wich option describes the context right

A) 80/140 is the portion that describes the book readers over all people surveyed

B) 31/63 just 63 people are relevant bc it's specified that we only consider beach travelers.

that also explains the 31, bc that's the number of beach travelers who'd like to watch a movie

C) 15/80 only 80 movie watchers in total, of whom 15 would prefer the city

Answer:

$f^{-1}(x) = 4x-3$ is the right answer.

Step-by-step explanation:

I the function is $f(x) = \frac{x+3}{4}$

$f(x)=\frac{1}{4}(x+3)$

Then we have to find inverse of function f(x).

we will write the equation as $y=\frac{1}{4}(x+3)$

4y = x + 3

x = 4y - 3

Now we will rewrite the function as

$f^{-1}(x) = 4x-3$

So the answer is $f^{-1}(x) = 4x-3$
