Step-by-step explanation:

\frac{(1-tan^{2}x)tan(2x) }{tanx} \\  but \:  \tan(2x)  =  \frac{2 \tan(x) }{1 -  { \tan }^{2}x }  \\ therefore :  \\  =  \frac{(1 - { \tan ^{2}x)(2 \tan(x))  }}{ (\tan(x) )(1 - { \tan ^{2}x })}  \\  =  \frac{2 \tan(x) }{ \tan(x) }  \\  = 2

Verify if 1/2x-2 and g(x) = 2x + 4 are inverses
Triss [41]
They are inverses if f( (g(x)) = x

f((g(x)) =  (1/2) (2x + 4) - 2  = x + 2 - 2 = x

so this proves that g(x) is the inverse of f(x)

the other inverse g((f(x))  should also be = x
