Explanation Given, y = − x 2 + 2 x − 4 Vertex formula. The vertex of the parabola y = a x 2 + b x + c has x coordinate − b 2 a and substitute the x coordinated in the original equation then we get y coordinate. Graph: y = − x 2 + 2 x − 4 Here, a = − 1 and b = 2 The x -coordinate of the vertex is x = − b 2 a = − ( 2 ) 2 ( − 1 ) = − 2 − 2 <

T1.4: Let ẞ(G) be the minimum size of a vertex cover, a(G) be the maximum size of an independent set and m(G) = |E(G)|. (i) Prove that if G is triangle free (no induced K3) then m(G) ≤ a(G)B(G). Hints - The neighborhood of a vertex in a triangle free graph must be independent; all edges have at least one end in a vertex cover. (ii) Show that all graphs of order n ≥ 3 and size m> [n2/4] contain a triangle. Hints - you may need to use either elementary calculus or the arithmetic-geometric mean inequality.
