Answer:
D) 504
Step-by-step explanation:
Having 9 members for elect president, vice-president and secretary
Then C₉,₃ = 9! / ( 9 - 3 )! = 9*8*7 = 504
Option B
the domain is all the real numbers, or (-infinite <x<infinite)
the range is y>=-4
axis of symetry is x= -1
vertex is (-1,-4)
the parabola opens upwards
x intercepts (-3,0) and (1,0)
y intercepts (0,-3)
hope this helps you. look it once
y=5/8
