Okay, i got this far:
f <- function(x) 0.25*x^2 + 6.47*x -32.6
g <- function(x) 0.99*x^2 -6*x -195
h <- function(x) 0.77*x^2 +14*x -495
j <- function(x) 0.001*x^2 + 65*x -785
k <- function(x) 0.9*x^2 -2*x -636
plot(x, f(x), xlab="Elemente in der Reihung", ylab="Indexwert des
Sortieraufwands"), type="l")
// lines(x, g(x), lty=3) //Not sure if it works, but this is
irrelevant atm.
As soon as R does the plot command, he states that x is an object he
can't
find.
So i propably have to do something like x <- XXXXXXXXXX. What do I
insert
for the XXXXXXXXX to make it have the values - say - from 15 to 10000?
x <- seq(15, 1000, by=5)
Thanks again.

You can certainly use "plot" but you could also use "curve":
> curve(0.25*x^2 + 6.47*x -32.6,0,10)
> f <- function(x) 0.25*x^2 + 6.47*x -32.6
> curve(f)
> curve(f,0,100)
