Question about finding where the function increases and decreases on .
I have been staring at this equation for a bit. Things I'm confused on.
the derivative of this is: now, how am I supposed to find where this derivative increases/decreases? Do I find the critical points first? by setting the derivative to 0? or do I solve it like cross multiply to make it: and if so once I square this does it make the result ? I'm really lost here and it seems like it should be easier.
Does setting the derivative to > or < or = and solving for the x give a critical point?
