Question 793133: Not sure how to make the "o" smaller than what I have it....
find (fog(x): (gof)(x): and (fog)(2)
f(x)=2x. g(x)=x+7
Answer by Cromlix(4381) About Me  (Show Source):
You can put this solution on YOUR website!
fog = 2(x + 7)
2x + 14
gof = 2x + 7
fog (2) = 2(2) + 14
fog (2) = 18
Hope this helps.
