I tried taking the derivative of the derivative and graphed that but it still gives me an image of 6 critical points.

NVM, TOTAL IDIOT HERE... I know what you're saying now. Thanks.

because when you plug in -1 for y=2x^3+24x-18 the end result is a negative not positive. The other choices to the questions are: b.decreasing for all values of x c.only increasing for values of x on the interval (-infinity,-2)U(2,+infinity) d.only increasing for values of x on the...

Homework Statement The first derivative of the function f is given by f '(x)= (((cos^2)x)/(x)) - 1/5 How many critical numbers does f have on the open interval (0,10)? Homework Equations The Attempt at a Solution I already got this question wrong but I don't know why I got it...

that makes sense, thanks for the tip. Never would have thought to use conservation of energy.
