Determine whether the subset of C(-o, 0) is a subspace of C(-0, 0) with the standard operations.
The set of all constant functions: (for example f(x) = c)
STEP 1: Check whether the set is closed under addition.
f(x) = c, g(x) = d
f(x) + g(x) =
Is the set closed under addition?
Yes
No
STEP 2: Check whether the set is closed under scalar multiplication.
f(x) = c
af(x)
Is the set closed under scalar multiplication?
Yes
ONo
STEP 3: Is the set a subspace of C(-∞, ∞)?
subspace
not a subspace
