hello,
this solution seems to be just about everywhere. Although it doesn’t chance my situation at all. I am using the image uploader in 2.9, but can neither see a preview nor edit the image uploaded. The message I receive when trying to edit the blank image is “Image data does not exist. Please re-upload the image.” However I have been wrestling with this for weeks, with no solution working. I am growing desperate in fixing this problem and was hoping for some help.
Thanks!

Comment on The Illinois Basic Skills Test by Jackie Ballarini

Not everyone who wants to become certified in IL graduated in IL. Not everyone who is studying to be a teacher recently graduated from high school (it hasn’t really been that long that the ACT has been part of the PSAE).

That said, it is not a good test. The cut-off scores for passing are a joke. 35% will get you a pass on the math portion. I’m afraid to look up the actual pass rate.

Dan: Thanks! I’m glad it was helpful. Unfortunately, the underlying grapher (currently gnuplot) expects the functions to be continuous. (It samples the function at a large number of points, and then connects them, in order to arrive at a rather accurate graph overall.)

Unfortunately, that means that it won’t handle discontinuities in the way one might like. (For example, a jump discontinuity would be drawn connected with a line, rather than disconnected.) Similarly, infinitely small holes won’t appear. You can, however, draw the hole on later manually in a graphics editor, if that helps in some way. I’ll consider adding the ability to add such points later, but at the moment, it’s effectively not possible.

Sorry, hopefully that explains things a bit. Thanks again.

Great App! It was prefect for one of my assignments. I was wondering if your app can sketch limits? For example. My prof gave me a question which is :
1. Sketch one possible graph of a single function ¦ that satisfies all of the limits below.

a. lim f(x) = 0
x ® -1 –
b. lim f(x) = -1
x® -1 +
c. lim f(x) = 1
x® 0
d. f(0) = 0
e. lim f(x) = 2
x® (infinite)

Jordan: You can do piecewise functions by graphing something like y = (x<1)(abs(x))+(x>=1)(x^2), which will give you the graph of abs(x) for x less than 1, and x^2 for x greater than or equal to 1. You can multiply by other conditions to add further conditions, generally using > or < will work. From there, add more terms to the sum in order to add more pieces to your piecewise function. (This has two side-effects: Where the piecewise function is undefined, the value will be zero, and vertical lines will be formed where there is a discontinuity.) Hopefully this helps.

Great app, but how do u do piece wise functions?

Eileen: Thanks for you enthusiasm! Also, thanks for pointing out that the labeling for zeros on the axes can be confusing. I’ve rewritten the tick-mark handling code to no longer label the points at the origin, as I’m unable to come up with any reason that those labels would be helpful.

If, on the other hand, someone comments that they would like the option to keep them labeled, I can add that as an option, although I think that at the moment, an extra feature to keep that labeled is unnecessary and would add clutter.

Thanks again! Hopefully this change helps make GraphSketch more usable.

Love this app!I use it to put graphs into my Word documents for quizzes and tests. One minor problem – the 0’s for labeling are confusing to my students. Is there any way to print the graph without the 0’s but with the grid lines?

Mary: As noted on the GraphSketch main page (under the "Please note" section), you will need to use root(x,3) to graph a cube root. (Fractional exponents don't work well with the software I'm using to produce the graphs. If I find a way to make fractional exponents more standard in the future, I will try to do so.) Thanks!
