what about the (5, 25) ? and the f'(5) part?


lol... what's to explain about that? You plug 5 into the derivative they give you and see what you get? Or you an put the derivative expression into wolfram search and see the graph. I'm not sure what you're asking for here...

I mean where would I add that? OR basically how would I input it into wolframalpha

wolfram is very user friendly

if you have your derivative func,etc , just simply replace your x's with the value you want

or type something like
derivative of x^3 - 4x^2 + 6x - 24 at x=5

I typed it out as you said, which one would be the answer or explanation out of all of these though?
/e ah I got it, thanks

Chain rule, as others have said.

FYI, don't hope to just get past this. The chain rule is pretty fundamental to calculus, it isn't going away next week when you start to learn new stuff. It is a central concept. If you fail to learn this you will be essentially screwed. So take the time to get it right.
