Simple Problem: Plotting mathematical functions
Hey there,
I want to plot 5 parabola functions, which happen to be
f(x) = 0.25x? + 6,47x -32.6
g(x)=0.99x? -6x -195
j(x)= 0.77x? +14x -495
k(x)=0.001x? + 65x -785
l(x) = 0.9x? -2x -636
in the same graph. Sadly I even do not really understand how to plot just
one graph...
I found this code in the Internet, which plots a cos-function:
>x <- seq( -10, 10, length = 1000)
>plot(x,
