Answer:
Step-by-step explanation:
7.
roots=-2,-1,1,3
critical points=(-1.5,-3),(0,6),(2,-13)
absolute minimum=-13
End behavior :approaches +infinity
Relative max=6 at (0,6)
Relative min. =-3 at (-1.5,-3)
and -13 at (2,-13)
interval of increase=(-1.5,0)∪(2,∞)
interval of decrease=(-∞,-1.5)∪(0,4)
8.
roots=-1,2
critical points=(0.5,10.5),(4,-10.5)
Abs.max/abs.min=not defined
End behavior:-∞ to +∞
Relative max=10.5
Relative min=-10.5
interval of increase=(-∞,0.5) ∪ (4,∞)
interval of decrease=(0.5,4)
