Question 15 Not yet answered Marked out of 2.00 P Flag question 1. Let X be an inner product space. Using the parallelogram identity to prove by few lines the Appolonius' identity: \lz – xl|?+||z – y|l2 = } [lx = y11° +2||2 - 5(x + y) + y) | 2. Prove that the norm function f(x) = ||*||: X → Ron a vector space X is continuous.
