please sove both problems im having trouble on them 

3. Let T : V → W be a linear transformation from a vector space V into a vector
space W. Prove that the range of T is a subspace of W. [Hint: Vectors in the range
of T have the form T(v) for some v in V.]
[p(0)]
[P(1)|
For example if p(t) = 3 + 4t + 5t² then T(p) = :
4. Define T : P2 → R² by T(p)
(a) Show that T is a linear transformation.
(b) Find a polynomial in the kernel of T.
(c) What is the range of T?
