Hi all,
I'm trying to plot this two curves in a single cartesian plane, but when I
plot the first one, the plot appears with no negative "y" value. When I plot
the second curve, it almost does not apear in the graph.
I was trying the plot.window but with no success.
Can someone help me with this?
If possible, I'd like to plot this curves in a perfect cartesian plane.
f = function(x) {
x^2
}
f2 = function(x) {
-x^2
}
plot(f,-10,10)
abline(h=0, v=0, col = "gray60")
curve(f2,col="orange", add=T)
Thanks in advanced!
