Answer:
62) vertex (-1,-4) x intercepts are (1,0) and (-3,0)
63) vertex (4,-4) x-intercepts are (6,0) and (2,0)
64) vertex (-3,-4) x-intercepts are (-1,0) and (-5,0)
65) vertex (-4,-1) x-intercepts are (-3,0) and (-5,0)
Step-by-step explanation:
16
Interval E contains (9,8,7,6,5,4,3,2,1,0,-1,-2,-3,-4,-5,-6)
so the numbers of the interval equals 16
