All questions need to be answered in a LARGE, LEGIBLE handwriting. i need to understand what your solving. Take your time and leave a detailed explanation of the question.

QUESTION (A,B,C AND D) need to be answered. Answers need to be UNIQUE.

7. The Adjacency Matrix a) Write out the adjacency Matrices for all the Tetris shapes. Draw vertices for every lxl block. (Not all matrices will be of the same dimension because some blocks will share more vertices than others.) b) What in the adjacency matrix tells you a graph is disconnected? (i.e. it is 2 or more connected graphs) c) What in the adjacency matrix tells you a graph has a vertex not connected to any other edge? d) Draw the graph associated to the following adjacency matrix TO 1 0 0 0 0 O 0 O LO 1 0 1 1 0 0 O 0 O 0 0 1 0 1 0 0 O 0 O 0 0 0 1 0 1 0 0 1 1 0 0 0 O O 0 0 O O 0 0 0 0 0 0 07 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 O O O O 1 0 0 0 0 1 O O O O 1 1 1 1 1 0 7.
