• yes
• no way to tell

For which of the following does g(x) not represent the inverse of f(x)?

• 
• 
• 
• 

Given that $f\left(x\right)\ =3x+5$   and  $g\left(x\right)\ =\ \frac{1}{3}x+5$ , find  $f\left(g\left(x\right)\right)$  . Are the two functions inverses of each other?

• x + 20 ; Yes they are inverses

• x + 20 ; No, they are not inverses

• x ; Yes they are inverses

• x ; No, they are not inverses
