Given function :
![f(x)=4x-2](https://img.qammunity.org/2023/formulas/mathematics/college/v1ufea4h7n4h5uzz9uvhkc7af8upaly1pc.png)
![g(x)=(x+2)/(4)](https://img.qammunity.org/2023/formulas/mathematics/college/uwx3boiu8ga8r7f7n0wsrxwfgrvqsls160.png)
For check the g(x) is a invers of f(x) the any value of x the f(x) output use as g(x) input then value of output of g(x) is equal to "x"
![\begin{gathered} f(x)=4x-2 \\ at\text{ x=2} \\ f(x)=4(2)-2 \\ =8-2 \\ =6 \\ \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/o0dhaqo3wybfmefoydzxpw6yhabwe4jktg.png)
for g(x)
![\begin{gathered} g(x)=(x+2)/(4) \\ \text{the f(x) output is 6 then:} \\ g(6)=(6+2)/(4) \\ =(8)/(4) \\ =2 \end{gathered}]()
so g(x) is a invers of f(x) .
The property show that convert any function to invers function then value of input convert in output and value of output convert in input that mean x change as y and change as x and above method full fill the condition.
