[R] expression input to a function

I am trying to write a function, which can be made very general if one of the inputs can be an expression. How can this be done?
For example, to find root of a function, I would like to say
my.func <- function(x) {x^3 + 2 * (x^2) - 7}
x.left <- 0
x.right <- 2
n.iterations <- 0
find.root <- function(my.func, x.left, x.right) {
# code here
return(c(x.mid, n.iterations))
}
The above method clearly does not work.
Thanks,
Naresh
