Which pair of expressions represents inverse functions

Natali5045456 [20]

Answer: C. $\dfrac{x+3}{4x-2}$ and $\dfrac{2x+3}{4x-1}$

Step-by-step explanation: if a function f(x) has g(x) as its inverse then it satisfies fog(x)=x and gof(x)=x

C. f(x)= $\dfrac{x+3}{4x-2}$ and g(x)= $\dfrac{2x+3}{4x-1}$

fog(x)=f( $\dfrac{2x+3}{4x-1}$ )

= $\dfrac{\dfrac{2x+3}{4x-1}+3 }{\dfrac{4(2x+3)}{4x-1}-2 }$

gof(x)=g( $\dfrac{x+3}{4x-2}$ )

= $\dfrac{\dfrac{2(x+3)}{4x-2} +3}{\dfrac{4(x+3)}{4x-2}-1 }$

hence C. is the pair of inverse functions
