+1491 When finding a derivatives, would using "y" instead of "f(x)" be the same thing? I saw y being used on my Calculus test today and I just wanted to know. If this is the case, then... I messed up bad... real bad.

Yes it is pretty much the same thing. Only the notation is really different.
eg
\(f(x)=5x^2+6x+7\\ f'(x)=10x+6\\~\\ wheras\;if\\ y=5x^2+6x+7\\ then\\ \frac{dy}{dx}=10x+6\\ or\\ y'=10x+6\\ \)
+1491 Thanks Melody! I really appreciate the clarification. Now if you'll excuse me, I'm going to go cry myself to sleep.
+118677 Come on High School Calc,
If you only put the wrong symbol out the front then you are not going to lose much marks - maybe not any...
+1491 It wasn't about the wrong notation it was more like seeing a y as function for the first time. I was so confused I literally focused on that question for 30 mins to no avail. Ended up losing more marks due to not answer a majority of easier questions. I need better testing habits. Anyways good night, the butts known as our district decided to throw us a suprise State Standards Test. Oh boy.
