Which comes first?

In Python a function is a value, so you can build $f \circ g$ as a new function. You will compose two machines and find where the order does not matter.

The idea. compose(f, g) returns a new function that does g first and then f.

Your tasks.

1. In compose, return the function $x \mapsto f(g(x))$.
2. Fill values with $(f \circ g)(x)$ for $x = 0, 1, 2, 3$, where $f(x) = x^2$ and $g(x) = x + 3$.
3. Fill same with the whole numbers $x$ from $-5$ to $5$ where $(f \circ g)(x) = (g \circ f)(x)$.
