Hey!, so i have the function f(x) = 3x^3-48x^2+162x+300
Now i only need the x0 to x10 points but geogebra includes x-100 to x1000 or something and it gets messy and hard to read..
How do i fix this? THANKS

what do you mean by "x0 to x10" points?

is this a software issue?

Hey, i posted something but it didn't appear because i had a link involved.
Ok so the problem is that this graph will first swing up, then down, then up. The last time it goes up, it goes straight up until infinity.
Now,i only need the start of this graph, not the last part where it's just a straight line upwards (like geogebra shows).
What i meant with x0 - to x10 is for f. so when x = 1, it's 3*1^3-48*1^2 , etc etc.
for example when x = 0, y = 300. But the problem is really geogebra. I could do this manually by hand, but i need to know how to do this in geogebra without it being a complete mess

adjust the x and y window ...

(1) right click ... select "graphics" (see attach#1)

(2) adjust window settings (attach#2)

... either that, or go to the tutorial

HI thanks a lot. I stumbled upon another problem.. And that is with the function : -0,01x^2 + 0,85x+ 2.20 . When i type that in the geogebra, it gives me an error with " illegal operation 0 ^ 2 " . Any idea what this means and how do i fix this? thanks

I cannot duplicate your problem ... works fine for me. I recommend you watch some tutorial videos.
