Dear R Helpers, I need to find the root of following equationy=x^2+3*x-1 by substitution a random number from less to more in the certain segment.I had tried using this codef <- function (x) x^2+x-12str(xmin <- uniroot(f, c(2, 4), tol = 0.0001)) but $ f.root : num -7.85e-07not 0, and so I'm not shure it's right code and satisfactory answer. Please guide. sveta
