Use a graphing utility to graph the function and to approximate any relative min

Question description

Use a graphing utility to graph the function and to approximate any relative minimum or relative maximum values of the function. (Round your answers to the nearest integer. If an answer does not exist, enter DNE.)f(x) = −2x^3 + 6x^2relative minimum (x, y) = relative maximum (x, y) =Use a graphing utility to graph the equation using each viewing window.y = −8x + 6Xmin = −5Xmax = 5Xscl = 1Ymin = −10Ymax = 10Yscl = 1Xmin = −5Xmax = 5Xscl = 1Ymin = −80Ymax = 80Yscl = 20Xmin = −5Xmax = 13Xscl = 1Ymin = −18Ymax = 12Yscl = 1Which of these viewing windows gives the best graph?firstsecond thirdall are equally good
