Anyone have a good site to explain how to work this problem? Friend just ask for help and she is not understanding what I am trying to tell her. Hoping I can point her to a tutorial.
@omnipotens don't you just plug the value in? I don't see the problem in that
@rnxpyke try explain that to over messenger to someone who is bad at math that is trying to help their child. That is why I was hoping for a link. They were just not understanding and honestly I have no idea on how to explain it.
@omnipotens maybe try out the stuff from khan academy. there is the video explaining function application:
and a task with a good explanation in the hint:
@rnxpyke awesome thanks! Math was always a weird area for me. In electronics I could calculate a formula that took a whole page and do it in my head. Give me the same form without the application and I was lost and could no longer visualize it. So when I explain things to people I have to always use visual cues so I can keep my own reference points correct.
@omnipotens Wolfram Alpha's been a good resource in my experience for both finding and understanding the solutions. Assumes the intermediary steps are accessible though, which could be an issue at times.
@omnipotens when someone says f(x), followed by f(-1/2) it's the same as making x = (-1/2)
