Approximate the critical numbers of the function on the open interval shown in the graph. Determine whether the function has a relative maximum, a relative minimum, an absolute maximum, an absolute minimum, or none of these at each critical number. X = none vFind the absolute extrema of the function on the interval [0, 00}. (If an answer does not exist, enter DNE.) f(x) = 8 22\" X + l absolute maximum (X, y) = ( 1,9 ) X absolute minimum (X, y) = ( 1,7 ) J
