Question

Determine for which interval(s) the function is increasing and decreasing.
y=|2x^2 + x - 6|

Answer 1

This is a lot harder than I'd want it to be... but, all the same,
\[\Large \frac{d}{dt}|t| = \frac{t}{|t|}\]

Answer 2

So, having said that, to find where the function is increasing/decreasing, we need its derivative.

Differentiate it :)

Answer 3

xD

Answer 4

I'm only in precal, we haven't learned much of anything about derivatives yet.

Answer 5

Sorry... maybe dan has something else up his sleeve :)

Answer 6

Something to do with its roots?
