Answer:
f(x) = (x- 10)(x + 4)
Step-by-step explanation:
We need to calculate -3+(-1), and then |....| gives positive number.<span>
|-3+(-1)|= | - 4| = 4</span>
The answer is the letter c and d
Find a compact form for generating function of the sequence 4, 4, 4, 4, 1, 0, 1, 0, 1, 0, 1, 0,
Zanzabum
The generating function for this sequence is
assuming the sequence itself is {4, 4, 4, 4, 1, 0, 1, 0, ...} and the 1-0 pattern repeats forever (as opposes to, say four 4s appearing after every four 1-0 pairs). We can make this simpler by "displacing" the odd-degree terms and considering instead the generating function,
where the coefficients of follow a much more obvious pattern of alternating 1s and 0s. Let
where is recursively given by
and explicitly by
so that
