1. Determine the intervals on which the graph is increasing, decreasing, or constant. 3- 2- 1- 5 4 -1- O A Decreasing on (- 00,0) O B Increasing on (- 00 , 4) O C Increasing on (-00,0) O D Decreasing on (00 , 4)Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if anyI and any symmetry with respect to the x-axis, the y-axis, or the origin. O A function domain: all real numbers range: {Fly S 9} intercepts: (4, 0), (0, 8), (2, 0) symmetry: none O 3 function domain; all real numbers range: {yly S 9} intercepts: (0, 41). (8, 0). (0. 2) symm airy, nnne O C not a function O D function domain: {x|x S 9} range: all real numbers intercepts: (1, D), (0= 8), (2, 0) symmetry; y-axis 5. Determine which graph defines a function.
