Here, I just plotted your equation onto the link that Melody gave you:
Hi AnimalMaster welcome to the forum.
I like to give helpful, incomplete answers.
I want this forum to be a learning site, not a cheat site.
If the asker posts a backup question asking for more help, and I do not answer fairly promptly, then your response may be welcomed but otherwise please do not answer over me.
I do not want you to feel down about me saying this. I know you have been answering lots of questions and I am really pleased that you have. Other people often may not feel the same. If I give a full answer then it is fair game for you and others to put your versions afterwards (or before) but if I do not finish, there is usually an obvious reason for this.
