Answer:
To find the inverse of:
Set the function to y:
Rearrange to make x the subject:
Swap x and y:
Change y to the inverse of the function sign:
Rewrite g(x) as a fraction:
Therefore, as the inverse of f(x) ≠ g(x), the functions are NOT inverses of each other
You wanna find a common denominator so put the problem like this
3 1/3.< You wanna take 3 (denominator)
And times it
By 5 then you wanna take the 5. - 2 2/5.< (deniminator) and times it by 3.
____ Your common denominator is 15
now it will look like this
3 1/15
-2 2/15
———-
Now subtract. You will need to borrow 1 from 3 since you cant subtract 2 by 1 so the 3 will become a 2 and the 1 will be come 11 and here you can subtract so this will be your answer.
2 11/15
-2 2/15
-———-
0 9/15
Thats your official answer 9/15 hope I helped :)
