Let V be the vector space of polynomials in the variable t of degree at most 2 over ℝ. An inner product on V is defined by
\(\langle f, g\rangle=\int_{0}^{1} f(t) g(t) d t\)
for f, g ∈ V. Let W = span {1 – t2, 1 + t2} and W⊥ be the orthogonal complement of W in V. Which of the following conditions is satisfied for all h ∈ W⊥?
1
h is an even function, i.e. h(t) = h(-t)
2
h is an odd function, i.e. h(t) = -h(-t)
3
h(t) = 0 has a real solution
4
h(0) = 0
