For example, could the polynomial:

$f(x) = x^2 + 3x$

Be written without $x$, using only the exponential, addition and multiplication functions, and high-order functions such as composition and partial application?

    What you just want is "Take a number, add $3$ to it and multply it by itself?" So you want "mult(sum(x,3),x)"? I mean, how would you "avoid" $x$ if you're considering indeterminate values?2012-11-18
