Find the absolute maximum value and absolute minimum value of the function (x)=x2−8x+7 on the interval [0,5]. (Give exact answers. Use symbolic notation and fractions where needed. Enter DNE if there are no such values.)
2) Find the absolute maximum value and absolute minimum value of the function (x)=9x⎯⎯√f(x)=9x on the interval [1,9].[1,9].
(Give exact answers using fractions if needed. Enter DNE if the value does not exist.)
3) Find the absolute maximum value and absolute minimum value of the function (x)=x2/3f(x)=x2/3 on the interval [−1,5].
