Graph each equation with a graphing utility using

(a) The specified window.

(b) The standard viewing window (for comparison).

1. y = 0.01x3 + 0.3x2 - 72x + 150

x-min = -100, x-max = 80;

y-min = -2000, y-max = 4000

2. y= - 0.0001x3 + 0.0015x2 + 0.6x + 7

x min = -100, x max = 100;

y-min = -50, y max = 50

3.

x min = -200, x-max = 200;
y-min = -0.02, y-max = 0.06
4.

x min = -200, x-max = 400;
y-min = -0.06, y-max = 0.01
