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?
