Question

Those who have guts and really think themselves math kings/queens , solve it

Answer 1

`g(x)=3x+2`

Explanation:

we have

`f(x)=2x` ----> linear equation

`gof(x)=6x+2` ---> linear equation

therefore

g(x)-----> will be a linear equation

so

Let

`g(x)=ax+b`

so

`gof(x)=a(2x)+b` ----> equation A

`gof(x)=6x+2` ----> equation B

equate equation A and equation B

`a(2x)+b=6x+2`

`2ax=6x ----> a=3`

`b=2`

Hence

`g(x)=3x+2`
