given the function f(x)=8/27^3-4/9^2-16/9x-1/27. Determine each of the following: Use the capital U button on vour keyboard for any unions of sets. Type the word infinity or -infinity for any infinities used in your answers. Lastly do no use any spaces between commas in your interval for solutions. Round any decimals to one place or the tenths. a- the intervals where f is increasing b- the intervals where f is decreasing c- the input for the local minimum d- the lical minimun value e- the input for the local maximum f- the local maximum value q- the interval where f is concave up h- the interval where f is concave down 1- the inpit for the inflection point x= i- the output of the inflection point y=
