How would I find f(x) such that (f of g)(x) equals g(x)? I attached the problem in the thing below. Any help would be greatly appreciated, thanks!

  f(x) = x^6

Step-by-step explanation:

The problem in the picture wants you to find f(x) such that (f of g)(x) equals h(x). That's a different question than the one in the statement accompanying the picture.

In h(x), the content of parentheses matches g(x), so we can see that ...

  h(x) = g(x)^6

For h(x) = (f of g)(x), this means ...

  f(x) = x^6

___

The answer to the question in your text is that you want f(x) = x.

Then f(g(x)) = g(x).

Bike B is better choice if Greg plans on owning the bike for 5 years or 6 years.

Explanation: Maintenance cost of $20 per year x 12 months x 6 years = 
     $1,440 annual cost compared to Bike A that has $2,592 annual cost. So, it is better to choose the lesser amount of annual cost.
