I was trying to get the complete set of numbers =>< on a concave graph using this f(x)=x^3+2x^2-x.
I was trying to simplify to 3x^2+4x-1 but I'm lost as to where to go next.
If f(x) is negative then slope is down and if it's positive then slope is increasing but there's 2 factors, increasing/decreasing and up and down parabola.
I was trying to attach a picture of the graph but I couldn't figure it out.
So I had X>=-3/2 for all the set of numbers so decreasing slope and facing down.
any ideas?? Thanks for help everyone.
FYI-My vocabulary may be wrong so I apologize.
