Do you know what a linear space is?

The standard way of proving "X is Y" is to use the definition of X to show that it also satisfies the definition of Y.

Here, X is the all functions, f, such that f(0)= f(1). Now, you need to show that that set satisfies the definition of "linear space"- that's just what Plato is asking.
