What is the slope for the function y = –3x^2 + 2 at the point x = 2?

OpenStudy (welshfella):

you need to find the derivative of -3x^2 + 2 then plug in x = 2 to get the slope

OpenStudy (tmagloire1):

y'=-6x -6(2)=-12

Thank you!

OpenStudy (anonymous):

was it right?

OpenStudy (welshfella):

yes

OpenStudy (tmagloire1):

The one on yahoo answers used a different point:-2 instead of 2. I just found the derivative and plugged in 2 like welshfella said.

OpenStudy (tmagloire1):

But thank you both
