Let V be the set of real-valued functions that are defined at each x in the interval (-∞, ∞). If f = f(x) and g = g(x) are two functions in V and k is any scalar, we define the operations of addition and scalar multiplication by W (f+g)(x) = f(x) + g(x), (kf)(x) = kf(x).

kindly answer it

a. Let V be the set of real-valued functions that are defined at each x in the interval (-∞, ∞). If
f = f(x) and g = g(x) are two functions in V and k is any scalar, we define the operations of
addition and scalar multiplication by
(f+g)(x) = f(x) + g(x),
(kf)(x) = kf(x).
Verify the Vector Space Axioms for the given set of vectors.
