For the function , Find
For finding inverse of x,
First let:
Now replace x with y and y with x
Now, solve for y
Taking 5th square root on both sides
Now, replace y with
So, the inverse of function is
Option A is correct option.
Let x represent the number.
.. x^2 +x = 2
.. x^2 +x +1/4 = 9/4 . . . . add 1/4 to complete the square
.. x +1/2 = ±3/2 . . . . . . . .square root
.. x = -2, 1
Numbers meeting that requirement are -2 and 1.
