how do I plot this in matlab?
f(x)=2x/(x^2)+1 - x/sqrt(3*x+6) in the interval of -2<x_<6 (what i mean is that x is smaller or exactly 6)
i wrote like this below:
x=linspace(-2,6)
f=(2*x/x.^2+1)-(x/sqrt(3*x+6))
plot(x,f)
but this did not work

Ran in:
x=linspace(-2,6) ;
f=(2*x./x.^2+1)-(x./sqrt(3*x+6)); %<--- element by element division
plot(x,f)
