Answer:
Step-by-step explanation:
AB = a
AP = 2PQ = 2QB
AB = AP + PQ + QB
= AP + +
AB = 2AP
AP = -----(1)
And we know QB =
QB= AP/2 = ---------(2)
Now midpoint of AP = ×
=
and midpoint of QB = ×
=
distance between these midpoints = -
=

Step-by-step explanation:
To show f and g are inverses we require to show that
f(g(x)) = x and g(f(x)) = x
f(g(x))
= f(6x - 4)
= =
= x
-----------------------------------------------------------------------------
g(f(x))
= g( )
= ( 6 × ) - 4
= x + 4 - 4 = x
-------------------------------------------------
Hence f and g are inverses
