Verifying an Inner Product for Continuous Functions

Please see the attached file for the fully formatted problems.

Suppose f(x) and g(x) are continuous real-valued functions defined for [0,1].  Define vectors in n, F= ( f(x1), f(x2), …,f(xn)) and G= g(x1), g(x2), …,g(xn)), where xk = k/n.  Why is n = 1/n  f(xk) g(xk) dx not an inner product for the space of continuous functions?

[0,1]. Define vectors in (n, F= ( f(x1), f(x2), …,f(xn)) and G=
g(x1), g(x2), …,g(xn)), where xk = k/n. Why is n = 1/n ( f(xk)
g(xk) dx not an inner product for the space of continuous functions?
