SUMMARY
The set of functions with a zero integral, defined as those functions f such that the integral from a to b of f(x)dx equals 0, is indeed a subspace of the vector space C[a,b]. This conclusion is based on the verification of the subspace axioms: the sum of any two functions in this set also has a zero integral, and any scalar multiple of a function in this set retains the zero integral property. The discussion clarifies that C[a,b] represents the set of all continuous functions defined on the interval [a,b].
