Answer: B
Step-by-step explanation:
To find the inverse function, you switch x with y and y with x. Then, you solve for y.
[switch x with y, and y with x]
[add both sides by 4]
[square root both sides]
[add both sides by 1]
Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.

Answer:
The ratio of non-winners in group A to non-winners in group B is
576 : 515.
Step-by-step explanation:
It is provided that, in group A, of the 720 people of the people will win $15 fuel cards.
The number of people winning the cards is:
Then the number of people not winning cards in group A is:
Also the same number of people win the cards in group B of 659 people.
Compute the number of people not winning cards in group B as follows:
Compute the ratio of non-winners in group A to non-winners in group B as follows:
Thus, the ratio of non-winners in group A to non-winners in group B is
576 : 515.
