Hi, Please have a look at the image, I need only the solution of part (c)

Please Dont tell me that the question is incomplete!

1. Let X = {r1, 2, X3, 14} and let b: X x X [0, 00) be symmetric with
b(x1, 2) = 3, 6(x2, T3) = 1, b(x2, x4) = 2.
Let c =0 and let m(x) = deg(x). Let f, g E C(X) be functions defined by
f(x1) = 1, f(x2) = 2, f(x3) = 3, f(x4) = 4,
g(r1) = 0, g(x2) = -3, g(r3) = 4, g(x4) = –1.
and
Ha) Calculate the inner product (f, g), and norms || f|| and ||g|| in l²(X,m).
X(b) Find || f – g|| -
c) Show that ||h|| = 0 for a function h E C(X) if and only if h = 0.
