(b) Let X= {ao+ax₁+a2x2+...+anxn, a;ER} be a vector space over R, write with prove a hyperspace and a hyperplane of X. مبر خد احمد Q₂ (a) Let M be a subspace of a vector space X, and A= {fex/ f(x)=0, x E M ), show that whether A is convex set or not, affine set or not. Write with prove an application of Hahn-Banach theorem. Show that every singleton set in a normed space X is closed and any finite set in X is closed (14M)arrow_forwardLet M be a proper subspace of a finite dimension vector space X over a field F show that whether: (1) If S is a base for M then S base for X or not, (2) If T base for X then base for M or not. (b) Let X-P₂(x) be a vector space over polynomials a field of real numbers R, write with L prove convex subset of X and hyperspace of X. Q₂/ (a) Let X-R³ be a vector space over a over a field of real numbers R and A=((a,b,o), a,bE R), A is a subspace of X, let g be a function from A into R such that gla,b,o)-a, gEA, find fe X such that g(t)=f(t), tEA. (b) Let M be a non-empty subset of a space X, show that M is a hyperplane of X iff there Xiff there exists fE X/10) and tE F such that M=(xE X/ f(x)=t). (c) Show that the relation equivalent is an equivalence relation on set of norms on a space X.arrow_forwardQ/(a)Let X be a finite dimension vector space over a field F and S₁,S2CX such that S₁SS2. Show that whether (1) if S, is a base for X then base for X or not (2) if S2 is a base for X then S, is a base for X or not (b) Show that every subspace of vector space is convex and affine set but the conevrse need not to be true. allet M be a non-empty subset of a vector space X over a field F and x,EX. Show that M is a hyperspace iff xo+ M is a hyperplane and xo€ xo+M. bState Hahn-Banach theorem and write with prove an application about it.
