Explanation:
______________________________________________________
Given the function:
______________________________________________________
" f(x) = x <span>− 2 " ; find the "inverse function" ;
______________________________________________________
Write as: " y = x </span><span>− 2 " .
______________________________________________________
Replace the "y" with "x" ; and the "x" with "y" ; and rewrite:
______________________________________________________
" x = y </span><span>− 2 " ;
______________________________________________________
Now, solve for "y" ; and isolate "y" as a single variable, on the
"left-hand side" of the equation:
______________________________________________________
</span>↔ " y <span>− 2 = x " ;
Now, add "2" to each side of the equation;
to isolate "y" on one side of the equation:
</span>→ y − 2 + 2 = x + 2 ;
→ y = x + 2 ;
Now, replace the "y" ; with: " f ⁻¹(x) " ; and rewrite:
_______________________________________________________
→ " f ⁻¹(x) = x + 2 " ;
→ which is: Answer chioice: [A]: " f ⁻¹(x) = x + 2 " .

6/7 is greater than 6/8. Think of it in terms of pizza. 6/7, you are able to feed 7 people. 6/8, you are able to feed 8 with the pieces, but it is the same size pizza, meaning that the slices get smaller then more people you are able to feed with it, or the smaller the slice. or you could put it into a calculator.
Answer:
The meet at first time at starting point after 336 seconds,
Vanu have completed 7 laps while Tanuj has completed 6 laps.
Step-by-step explanation:
Given that Venu and Tanuj take 48 seconds and 56 seconds to
complete a lap respectively.
To meet them again at the startiong point, the time taken must be multiple of 56 and 48.
So, the minimum time required to meet them again at the startiong point is time taken for first time meet.
Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.
