the points (-6,0)(-2,0)(1,0)(3,0) all exist in the graph which is only correct for the second graph to make your self even more sure
since the zeros are given and it ia a polynomial you can figure out the facrored form
which will yield
f(x)=(x+6)(x+2)(x-1)(x-3)
conducting a simple sign test
------------------------------------------'
there will be 4 critical values
-6 -2 1 3
before -6 the sign of f(x) -*-*-*-= +
after -6 and before -2 the sign of f(x) +*-*-*-=-
after -2 and before 1 the sign of f(x) +*+*-*-=+
after 1 and before 3 the sign of f(x) +*+*+*-=-
after 3 the sign of f(x) +*+*+*+=+
which only fits the upper right graph
1/5 of 400 = 80
400 x 1/5 = 400/5
400/5 = 80

Answer:
(answer in explanation)
Step-by-step explanation:
so, whenever you divide factorials, as soon as you get it to be the same ! on the top and bottom of the fraction, they cancel out like any other fraction would.
So, lets say you're dividing 55! / 50!
55! can also be thought of as 55 x 54 x 53 x 52 x 51 x 50!
= 55 * 54 * 53 * 52 * 51
Then you can simply solve the remaining equation
( 55 * 54 * 53 * 52 * 51 = 417,451,320)
hope this helps!!
