Restriction of a convex function to a line f Rn → R is convex if and only if the function g R → R, g(t) = f(xtv), domg = {t xtv ∈ domf} is convex (in t) for any x ∈ domf, v ∈ Rn can check convexity of f by checking convexity of functions of one variableA B c b D B B N b O b E M U v W P F L T y x Q G B S b r b H K b j b i b MerryNoel Chamberlain, MA, Teacher of Students with Visual Impairments NAME_____ C = PURPLE C = PURPLE C A C K S C C B J C R C C D C L Q C C E I C P C C F C M O C C G H C N C MerryNoel Chamberlain, MA, Teacher of Students with Visual ImpairmentsT E C H N I C A L S E RV I C E B U L L E T I N 2 3 L E c o B o o s t I l l u m i n a t e d M I L W i t h D T C P 0 0 6 8 O p e r a t e d A t O r A b o v e © 2 Recombinant Human Fgf Basic Fgf2 Bfgf 146 Protein 233 Fb 025 R D Systems ƒn[ƒtƒAƒbƒv Žq‹Ÿ ƒsƒAƒm "•\ ‰ï "¯Œ^ ƒAƒbƒv
