Let v be the space of twice differentiable functions on r satisfying f"-2f'+f=0 . define t:vrby t(/)=(s(0).s(0)) . then t is (a.) one-to-one and onto. (b.) one-

Let V be the space of twice differentiable functions on R satisfying f"-2f'+f=0 . Define T:VRby T(/)=(s(0).s(0)) . Then T is (a.) one-to-one and onto. (b.) one-to-one but not onto. (c.) onto but not one-to-one. (d.) neither one-to-one nor onto. please explain what is the answer and how?
