Question

PLEASE HELP ME PLEASE

Answer 1

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) = (g(x)-1)/(3)`

`(f \ o \ g)(x) = ((3x+1)-1)/(3)`

`(f \ o \ g)(x) = (3x+1-1)/(3)`

`(f \ o \ g)(x) = (3x)/(3)`

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

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

Answer 2

x

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
