New function by adding two functions

Question

Is it possible to create a new function from the addition of two other functions in Julia? I want to do something like this:

function quadratic(x)
  return x^2
end

function cubic(x)
  return x^3
end

f::Function = quadratic + cubic
# such that f(x) returns x^2 + x^3

Answer 1

There is the less magic solution which is f(x) = quadratic(x) + cubic(x)
