How do you graph a function on a graphing calculator? Specifically this one:
http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
trying to graph: f(x) = 1/5(x + 4)^3
THIS IS AWFUL

Put a (*) between your 1/5 and (x+4)^3. Then it will graph.

Good at math. Never used a graphing calculator. :cool:

I don't know/care what a function is but this chapter is chocked full of questions about them. Very angering.

Bet I could whip it out in 5 mins. :cool:
Kind of a nerd like that.

orly? THIS IS A TEST: (for testing purposes only)
One question has a graph and it has points at -2.4 and 2.2 and a curvy line thing between them (above the X line) and says that shows y=f(x)
It wants the answer for y=f(-x)

Multiply your function by a negative (-) and regraph. :cool:

Wait did it give you a function? Or just wants to know y=f(-x) for the two points?
-
It gives the function of y=f(x)
It wants to know the points for y=f(-x) and graph it
-

Should mirror itself at the point where it croses the x-axis.
Edited for clarification.
-
It doesn't cross the x-axis, it crosses the y-axis. (the one going up and down)
-

It doesn't cross the X-axis at all? Zoom out on your graph to make sure. Is it a U shape graph that doesn't cross the x-axis?
-
need to know if the function is even or odd....
Is it symmetric about the y-axis? if so, its an even function and then the graph will be the same f(-x) = f(x)
If it is anti-symmetric (mirrored about the line y=x) then it is an odd function and f(-x) = - f(x)
If it is neither then you don't have enough info to say without the explicit function.
-
No idea what any of that means. How bout you just give me the answer, bub. :cool:

would love to, but I need to see the graph.
Are the all of the points in your graph postive?
IF so then I bet its an even function, and then the graph of f(-x) would look exactly like f(x)

The two points given to him are not the same, both above the X-axis. One is positive, the other is negative. -2.4 and 2.2 if I recall correctly? This would not make it symmetrical about the Y-Axis if the X directions of the points is -2.4 and 2.2.
Definitely need to see a graph.

I failed college algebra the first time bc I had no idea how to use one.

At nearly mid-semester of College Algebra I still have no idea how to use one. Very intimidating.
-
Why not just post the question?
-
just flip it about the y-axis
I was making life too complicated (since this is a function).

That's not fracking math, it's torture. Anyone not an engineer or rocket surgeon has no need for that kind of chit. Colleges would better prepare people by offering more comprehensive stats/research classes that involve real-world math.

AGREED. I don't have a use for anything beyond 6th grade math, really.

How do you do meaningful statistics without functions?

How do you do meaningful statistics without functions?
You can't, but college algebra has to be the worst way to go about introducing the concept to the general population. You'd be surprised at the number of people that can't figure out, let alone understand, how their property taxes are calculated or that mill levies/property valuations are irrelevant independently. These are the same people that have no understanding of poll results or what may skew poll results (eg biased questions). There's a lot of ways to go about teaching the concepts that don't involve finding x,y and z that would greatly improve the public's understanding of complex equations in our world.

You don't do statistics.

Saul, I'm good at teaching math, at least better than the non english speaking TA you have. Anyways, this site (wolframalpha) is a type of AI. Anticipates what you want with specific functions you enter. I use it to make sure I'm doing things correctly, much cheaper than a solutions manual too (free).
http://www.wolframalpha.com/input/?i=f(x)+%3D+1/5(x+%2B+4)^3 (http://www.wolframalpha.com/input/?i=f(x)+%3D+1/5(x+%2B+4)^3)
It will show you the graph and any other things. :cool: :kstatriot:

I figured Saul was too old to be in college. Don't know why. :dunno:

College Algebra :facepalm:

True story: Panda is not very good at math. When I took college algebra the teacher liked me cause I was funny. He would walk me through every one of our tests and let me repeatedly re-do the problems until I got them right. For the final I was only able to answer 8 out of the 17 questions. I turned it in and he just looked at me for roughly 15 secs and then was like "go sit down and get the hell out of my face." He then went on to answer every question for me, including the 8 I had attempted to do. I got a perfect score on the final and a 98% in the class.

No. Actually, quite the opposite.

True, yet sad story:
One of my college professors wanted to show off how he had PI (3.14.....) memorized to 100 decimal places. This was supposed to be during our Finals review.

Of course you didn't. It's just college algebra. You get college credit for your high school calculus class.

Your momma’s so fat that the probability that she is in an arbitrary point in a room is 1
-
Yo momma is so fat, the recursive function int yourMom{ (return yourMom();} causes a stack overflow
-
Yo momma’s so fat that when I used multiple integration to find the volume under her curves, it turned out she was a hypervolume and could not be graphed.
-
Your momma's so fat that her weight can't be estimated using a t-distribution, since her fatness doesn't provide any degrees of freedom.

Biz Calc was another class I had to use my skills of seduction to pass. Thank you Becca.
