Question

If g(x)= 2x and fog(x)=6x-2, find f(x) , where f(x) is a linear function.

Answer 1

Answer:

g(x)=2x and fog(x)=6x-2

g(x)and fog(x)= f(x) -(1)

f(x)= 2x+6x-2

-2x-6x=2

-8x=2

x=2/8

x=4

hence, x=4

so, f(x) is equal to f(4)

Answer 2

Answer:

Step-by-step explanation
Here
g(x)= 2x
fog(x)= 6x-2

 fog(x)=f(g(x))

or,6x-2=f(2x)

or,f(2x)=3(2x)-2
thus,
f(x)=3x-2
