To find an inverse function:
1. Write the function.
2. Replace f(x) with y.
3. Switch x and y.
4. Solve for y.
5. Replace y with
Now let's follow the steps above and do it.
1. f(x) = 4x
2. y = 4x
3. x = 4y
4. y = x/4
5.
Answer:

Step-by-step explanation:
Using proportion to find the teachers required x, then
= 
( cross- multiply )
221x = 3536 ( divide both sides by 221 )
x = 16
The number of teachers required this year is 16

Step-by-step explanation:
Answer: 9.
Step-by-step explanation:
8 5/6 is a mixed number with a whole number and a fraction. We want to round to the nearest whole number without the fraction.
First, we convert the mixed fraction to an improper fraction or fraction like this:
((8 x 6)+5)/6 = 53/6
Then, we divide the numerator by the denominator from the previous step:
53/6 = 8.83
Now we have one decimal number. Round using the following rules:
If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.
If the number to the right of the decimal point is less than .5, then leave the number to the left of the decimal point as is.
.83 is .5 or higher. Thus, we add 1 to the left of the decimal point. 8 5/6 rounded to the nearest whole number is therefore the answer will be 9.
