1. 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) =x³+3x²

^{2. Find the domain... 4/ (x^2 -9x)}

3.Use a graphing utility to graph the equation using each viewing window. y = -4x+5

Xmin =5 Xmax = 5 Xscl = 1 Ymin =10 Ymax = 10 Yscl = 1

Xmin =5 Xmax = 5 Xscl = 1 Ymin =40 Ymax =40 Yscl =10

Xmin =5 Xmax = 13 Xscl = 1 Ymin =7 Ymax =10 Yscl = 1

Which of these viewing windows gives the best graph?
