What are critical numbers? numbers needed to solve problems values of x that cause a derivative to be equal to zero values of y that cause a derivative to be equal to zero values of x that cause a derivative to be undefined both b and d
How are relative extrema related to critical numbers? There is no relationship between critical numbers and relative extrema. Every relative extrema occurs at a critical number. Every critical number has a relative extrema. Critical numbers are only found at relative extrema. none of the above
Find the critical number(s) of the following: x = 1 x = 1 x = 0 undefined none of the above
Find the relative extrema for the following function: (1, 6) (1, 4) (0, 5) no relative extrema none of the above
Find and describe all extrema for the following function: on the interval Absolute max: (1, 4)  Absolute min: (2, 13)  No relative extrema Absolute min: (1, 4)  Absolute max: (2, 13)  Relative min: (0, 5) Absolute min: (1, 4)  Absolute max: (2, 13)  No relative extrema No extrema  none of the above
