First you must know that f(x) means the same thing as y so...
y = 9x - 8
To find the inverse switch the places of x and y and solve for y
x = 9y - 8
x + 8 = 9y
^^^That means the answer is A!
Hope this helped!

Using the Central Limit Theorem, it is found the correct option regarding why the large-sample confidence interval for these data.
c. Because there are only 6 skaters in one group having wrist injuries.
<h3>What does the Central Limit Theorem state?</h3>It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean and standard deviation
, as long as
and
, that is, as long as there are at least 10 successes and at least 10 failures in the sample.
In this problem, for the sample of people wearing wrist guards, only 6 had injuries, hence the large-sample confidence interval should not be used and option C is correct.
