It should be the square root of 2 (~1.141)
A one-to-one function has an inverse. The inverse is another function that undoes the action of the first one, so if we evaluate a function 
at some point 
to get the number 
, evaluating the inverse at will recover the original input . In other words,
The process works in the opposite direction, too:
From the given definition of 
, we have 
, so taking inverses on both sides, we find
Given 
, evaluating 
at its inverse will recover , so that
is another way of writing the compound function 
. As already discussed, this reduces to , so

Answer: 2/3
Step-by-step explanation:
Slope is defined by Rise/Run, so if the staircase extends vertically (rise) by 2 meters, and the staircase extends horizontally by 3 meters, then using the rise/run format you end with 2 meters over 3 meters. (2m/3m or 2/3)
Hopoe this helps!
The equation for a line with slope m through point (h, k) can be written in "point-slope" form as
.. y -k = m(x -h)
You have m = -4, (h, k) = (-2, -6), so the equation of your line is
.. y +6 = -4(x +2)
