Hello Tutor, please help me with these problems. Please write neatly and ONLY SOLVE THE "CIRCLE" ONES. Thank you so much for your help. I will really appriciate your help and I would leave a good feedback and a thumbs up?

28. Let V = CO[-1, 1] with the inner product (f, 8) = f(x)g(x) dx - 1 and W = {f E V | f(- x) = f(x)}. a. Show that W is a subspace of V. b. Show W- = {f E V | f(-x) = -f(x)}.6 21. W = span N HOW ANO - V = -17. W = span OON V =In Exercises 16-21, W is a subspace of R" with the standard inner product. If v is in R" and {w1, . .., Wm) is an orthogonal basis for W, then the orthogonal projection of v onto W is given by-1 19. W = span NW V =
