help please

Suppose 1 = (a. b), w = (c. d) ER , and suppose we impose a new B dot product defined by C (a, b) * (c, d) = 7ac + 8bd D (av) * 1 = (1 *0) determine the axioms satisfied by such product * E 10=0 +7=0 A F none of these Suppose our vector space is the collection of real polynomials of degree B if # is the angle betwen f and h, then.. 2 or smaller, and suppose we define the dot product "*" as follows p(x) * q(x) =p(-1)q(-1) + p(0)q(0) + p(1)q(1) cos(0) = 33 Vi1V3 Furthermore suppose C * is an inner product in V f(x) = x-tr+l, g(x) = -2x-+2x-3, and h(c) =2x-+2x- D 1/h(x)|| = 2V3 E 1If (x)|| = V21 Select the true statement/'s F projjh = ja+x- G A 1/h(x)|| = V37 H none of these
