1.
The function f(x) is increasing in (-2,0)u(0,2). You could tell from the graph because the outputs of f'(x) are positive and the slope for f(x) is positive so this means that that is incrasing. The graph is decreasing in (-&,-2)u(2,&). You could tell bcuz the outputs for F'(x) are negative so the slope for f(x) is negative and that's how you tell that is decreasing.
2.
There is an extrema in -2,0, and 2. It exists an extrema there because the slope of those points are zero and every time the slope o fa certain point is zero there is an extrema.
3.
There is a concave up approxamately at (-&,-1.2) You could tell that it has a concave up here because it holds water in this certain space of the graph. There is also a concave down at (-1.2,0)u(o,&). You could tell that is a concave down because instead of holding water its like you could say is covering something or throwing all the water that was holding.
4.
I say It woul look x to the power of 4 bcuz the other graph is to the power of 5. meaning like this is the deravative you need to see how its original power was.

Mindset!!
well well well...
1. Acoording to my mindset I wouln't know in what specific category I am. But what I do know is that I improved a lot now when it comes to intellegence. Now I take the things more seriously. And I'm liking it because things become easier.
2.Well like I said. This mindset has improved my skills real good. Now I think that every problem has its solution. I'm not talking just matemetically, in real life is the same thing if you use this technic it will help you a lot.
3.I'm not saying that life is perfect because finding the answers to questions that seem to have no answer you panic and it makes the things harder. My reaction to this was very surprise and unbeliveble. How a very little tiny thing could do big things.
4.My future, this is gonna absolutelly help me, where ever I am at. It makes you feel in a higher level. You think in a higher level and get things faster. I love this technic or whatever this is that is doing to my mind.

The Limit? what's the limit?
Limits, I kind of get some limits but when I get to a limit that I dont understand I go crazy and feel like hitting my head to the wall.:( I knoow...
well so I think I do need help!!plzzzz
The ones that I kind of dont understand are in pg.95 #11,#13 and 14.
when the function has numbers and x's or y's I get it but when it has sin,cos,tan,etc. or e,int. I dont get it. that's the only problems that I am having problems with.
When someone explains me a problem detail by detail
I always understand it the first time. So I need help detail by detail.

Tips and Hints
Allllllrighttttttttt TRIG.
I think thig is all about the unit circle. The unit circle is easy. To know the unit circle from head to toe you have to know the firsr quadrant of the unit circle. The unit circle has 4 quadrants. I think you know why they call it quadrants.(well if you dont know is b-cuz the circle is divided in 4 quarters) like I Said if you learn the first one you should not have trouble in knowing the other three. Sin and Cos think as your (x,y) X is cos and Y is Si :)
I dont think trig. confuses me but if it confuses you I think I'm Pretty good in the unit circle. Have any Q's feel free to ask me.

Inverse and Logarithm????
well need help...
I kind of know inverse one of the examples for inverse would be
Inverse of f(x)=2x is log2x you cant plug the x on top of the 2 but x supposed to be on top of the 2 and in the log, the 2 in the bottom of log and the x is in top of the blog. sorryyyyy..hope you understand it.
but I still have trouble graphing logarithms
Help help.!!!!
