if f(x) =1+x/1-x how do u find 1)f^-1 (x) 2)f^1 (x)?
if f(x) =1+x/1-x which is true?
Options:
1.
f-1(x) f(x) = 1
2.
f-1(x) f(x) = -1
3.
f-1(x) = f(x)
4.
f-1(x) - f(x) = 2

sum up to infinite series is?
It is very easy to remember the ID number of my ATM card which is a nine digit number and every digit is distinct. If i tell you some clues then you will be able to find it.Consider my numer as PQRSTUVWX corresponing to 1 to 9 digits though not repository .The Id is divisible by 9. if you delete the digit at its units place, the remaining 8 digit number of my ID is divisible by 8. If you again delete the last digit of the 8 digit number the remaining 7 digit number is divisible by 7 and the process goes on
.1) What is the sum of the digits of the ID number of my ATM card?
a) 55 b) 45 c) 90 d) Cannot be determined
2) Find the first five digits from the Following
.3) Find the last five digits from the following.
4) Find the nine digit id of card
.5) Which number does letter R represents.
