Question

if f(g(x))=x and f(x)=3x-4, find g(x)
a.g(x)=(x-4)/3
b.g(x)=(x+4)/3
c.=(x/3)+4
d.=(x/3)-4

Answer 1

u have to check it by putting the value of g(x) in place of x in f(x) eqn.if it comes to x then dats the g(x)

Answer 2

try first one to check! r u getting me?

Answer 3

but i dont know what g(x) is for me to find f(g(x))

Answer 4

we have to find g(x)
we have to find it by puting all the options in f(x) eqn which is given.
