This is completing the square:
(x^2+12x+36)+42-36
Answer: (x+6)^2 +6
Answer:
Step-by-step explanation:
mean=(4+5+5+6+6+7+8+8+8+9)/10=66/10=6.6
x |x-6.6|
4 2.6 (6.6-4=2.6)
5 1.6 (6.6-5=1.6)
5 1.6
6 0.6 (6.6-6=0.6)
6 0.6
7 0.4 (7-6.6=0.4)
8 1.4 (8-6.6=1.4)
8 1.4
8 1.4
9 2.4 (9-6.6=2.4)
-----
14.0
------
mean absolute deviation=14/10=1.4
Answer:
F(2)=3
Step-by-step explanation:
The first term is -1.5= f(1).
So F(1+1)=-2*f(1)= (-1.5)*(-2)=3
