Answer:

Graph y=0.5x^2 | Mathway

Focus: (0,0.5) ( 0 , 0.5 ). Axis of Symmetry: x=0 x = 0. Directrix: y=−0.5 y = - 0.5. xy−22−10.50010.522 x y - 2 2 - 1 0.5 0 0 1 0.5 2 2. image of graph. y=0.5x2 y = 0 

b)

 (2 3 A = (: #) e M2(Z/26Z). Solution. Here D = 2 - 8 – 3 - 7 = –5 = 21 in Z/26Z. Since g.c.d.(21,26) = 1, the determinant D has an inverse, ...
