Question

:) got to love math lol

Answer 1

I'm currently learning this but what I'm being taught is different, after the question there should be an integer. It should look like this, (f (open circle) g)(any number) Due to the lack of number I'm not sure what to do. If there was a number then you plug that number into g and whatever you get you plug into F. 

Answer 2
