Hey there :)

f ( x ) is y 
So here, f ( x ) = x - 2
Which is       y = x - 2

To find an inverse of a function, just exchange x and y places
And solve for y

x = y - 2

Take 2 to the other side to isolate y
[ You do addition when you see subtraction ]

x + 2 = y

Your answer will be Option D) f⁻¹ ( x  ) = x + 2
