Find the average rate of change For the function below from 1 to 4. 3 x+2 f(x) = Determine any maximum. 2+ X O A no maximum O maximum at (0, 2) B O maximum at (- , 2) C O local maximum at (- 1, 2) DGraph the function. f(x) = [-x+2 ifx O B Range: y > 0 Yes, it is a function. 0 Domain: positive integers C Range: positive integers No, it is not a function. 0 Domain: x 2 0 D No, it is not a function. Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if any, and any symmetry with respect to the x-axis, the y-axis, or the origin. O A function domain: all real numbers range: {m s 9} intercepts: (1, 0), (0, 8), (2, 0) symm etry: none 0 B not a function 0 c function domain: all real numbers range: {Fly 5 9} intercepts: (0, 4), (8, 0)= (0, 2) symmetry. none 0 D function domain: {x|x S 9} range: all real numbers intercepts: (4, 0), (0i 8). (2: 0) symmetry: yaxis Determine the intervals on which the graph is increasing, decreasing, or constant. '"N k; Decreasing on (- 9 ,0) O 3 Increasing on (- 0, 4) O C.
