Supremum norms for quadratic polynomials

• We define two norms on R-3 as follows. For (a, b,c) is an element of R-3, we let parallel to (a, b, c)parallel to (R) = sup {/ax(2) + bx + c/ : x is an element of [-1, 1]} and parallel to (a, b, c)parallel to (C) = sup "/az(2) +bz +c/ : z is an element of
