If there are no such values, type DNE. If there are multiple discrete values, separate them with commas. If there are a whole interval of values that fulfill the requirement, use interval notation to give all of the values in the interval. Type oo for oo and -oo for -00. Also type U for U. t -3 +2 1 0.5 0 1 2 3* -0.5 +2 I -1+ -1.5 -2+ Where is f'undefined? at x What is the global minimum of f? Where does it occur? the global minimum is which occurs at I What are the critical values of f? at x Where does f have local minimums? at x Where does f have local maximums? at What is the global maximum of f? Where does it occur? the global maximum is x = Where is f'> 0? Va in the interval Where is f' < 0? Va in the interval which occurs at
