H. c-intercepts: about -2 and 2,
y-intercept: about - 4
R. positive: -5 < x < 1, negative:
x < -5 and x > 1, increasing:
x < -2, decreasing: * > -2,
y-→-o as I — to and
V →-o as X -> -
Approximate when the function is positive, negative,
increasing, or decreasing. Then describe the end
behavior of the function.
