[SOLVED] easy second derivative question
"If y^2 - 3x =7 what is the second derivative?"
Answer choices:
A) -6/7y^3
B) -3/y^3
C) 3
D) 3/2y
E) -9/4y^3
I got the first derivative to be: 3/2y
Second derivative: -6/(4y^2)
I cannot for the life of me figure out what I did wrong, but I know it's something since that's not a choice. I've been messing up a lot lately, so I think I'm making some sort of vital error. A step by step explanation would be appreciated!
You guys are so awesome here, thank you for all that you do.
