Plot in cartesian plane
...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!

The condition has length > 1 and only the first element will be used
...rst
value of x.
What I'm doing wrong here?
mod = function(x) {
if (x < 0) {
mod <- x*(-1)
}
else {
mod <- x
}
}
f = function(x) {
f <- mod(x)/x
}
x <- seq(-1,1,0.01)
x
y <- f(x)
y
plot(f,xlim = c(-1,1))
remove(x,y,f,mod)
best regards,
