Question

PLEASE HELP ME PLEASE

Answer 1

Answer:

x

Step-by-step explanation:

f(x) = (x-1)/3

g(x) = 3x+1

f(x) °g(x) =

Substitute g(x) in for x in the function f(x)

f(x) °g(x) = (g(x) -1)/3

             = (3x+1 -1)/3

             = 3x /3

             =x

Answer 2

Step-by-step explanation:

Step 1:  Find $(f \ o \ g)(x)$

What this basically means is that you substitute the equation of g(x) into the x's of the function f(x)

$(f \ o \ g)(x) = \frac{g(x)-1}{3}$

$(f \ o \ g)(x) = \frac{(3x+1)-1}{3}$

$(f \ o \ g)(x) = \frac{3x+1-1}{3}$

$(f \ o \ g)(x) = \frac{3x}{3}$

$(f \ o \ g)(x) =x$

Answer: Option D, $(f \ o \ g)(x) =x$
