Find the inverse of the function.

f(x) = x3 - 8

Step-by-step explanation:

To get inverse function , follow the steps

Replace f(x) by y

Swap the variables x and y. Replace x with y and y with x

, solve the equation for y

Add 8 on both sides

To remove cube , take cube root on both sides

Now replace y with f inverse

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
