In f(g(x)), g(x) acts as a variable.
If and
f(x) = 5x + 11 / 4
g(x) = 4x - 5 / 11
i need to evaluate f(g(x)) and based upon the solution state wether the functions are inverse, would help gratefuly! only bit im really struggling on! wathed vids on u tube and read about 10 books but dont understand, even is someone points me in the right direction, ive tried swapping the x with a number to see if there inverse but i donth think they are, any help gratefully appreciated
