The function f\displaystyle {f} is graphed below. State the values that fulfill the following requirements.

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 \displaystyle \infty and -oo for \displaystyle -\infty. Also type U for \displaystyle \cup.


Where is f=0\displaystyle {f}'={0} ?
at x=\displaystyle {x}=

What are the values in the closed interval [1.2,1.5]\displaystyle {\left[-{1.2},{1.5}\right]} where f\displaystyle {f}' undefined?
at x=\displaystyle {x}=

What are the critical values of f\displaystyle {f}?
at x=\displaystyle {x}=

Where is f>0\displaystyle {f}'>{0}?
x\displaystyle \forall{x} in the interval  

Where is f<0\displaystyle {f}'<{0} ?
x\displaystyle \forall{x} in the interval  
Where does f\displaystyle {f} have local minimums? What are these local minimum values?
the relative minimum is which occurs at x=\displaystyle {x}=



Where does f\displaystyle {f} have local maximums?
the relative maximums occur at x=\displaystyle {x}=

Where does f\displaystyle {f} have absolute minimums? What are these absolute minimum values?
the absolute minimum is which occurs at x=\displaystyle {x}=

Where does f\displaystyle {f} have absolute maximums? What are these absolute maximums values?
the absolute maximum is which occurs at x=\displaystyle {x}=
