I am sorry if i am wrong but i am getting c or d
The inverse of this function is y = 
You can find the inverse of any function by switching the x and y values. Once you've done that, you can solve for the new y. The result will be the inverse of the function. The work for this one is below.
y =
----> Switch the x and y
x =
-----> Add 9 to both sides
x + 9 =
----> Take the natural log (ln) of both sides. This will case the e to cancel on the right side.
ln(x + 9) = 2y ----> Divide both sides by 2.
y = 
This will be your inverse function.

Answer: K = 6
Step-by-step explanation:
If you find the inverse of the inverse function, it will return back to initial function.
The inverse of r^-1 (x) will give r(x).
To find the inverse of r^-1(x), let it be equal to y. Interchange y and x for each other and make y the subject of formula. That is,
Y = 2x^2 - 14
Interchange y for x
X = 2y^2 - 14
2y^2 = x + 14
Y^2 = x/2 + 14/2
Square both side
Y = sqrt ( x/2 + 7 )
It is only when K = 6, that will can get the value above.
Deviation means possible distance in between sometimes 52,300-8,260 is 44,050 so that rules out b because 36,875 us belie 44,050 making the answer a but its always best to check anyways so 52,300+8,260 is 60,550 and 56,236 is in 60,550 so the answer is A
