  1. Do not ping the Moderators, unless someone is breaking the rules.
  2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
  3. Do not ping other members randomly for help.
  4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  5. Wait patiently for a helper to come along.
  6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

+close
Feel free to nominate the person for helper of the week in #helper-nominations
If you're happy with the help you got here, and the server overall, you can contribute financially as well:

From what I worked out
f(g(x)) = f(x+5) = (x^2+5)-7 = x^2-2

snow flume
#

(x+5)^2 - 7

#

$$ f(g(x)) = g(x)^2 -7 $$

#

what happened to the x+5?

#

or do i substiture for g(x)
g(x+5)^2-7?

snow flume
#

you substitute g(x) = x+5

#

$$ f(g(x)) = g(x)^2 -7 = (x+5)^2 -7 $$
