Answer:
C (-8-i)
Step-by-step explanation:
114. This would make 112 the smaller one
114
+112
-------
226
We can apply some rules backwards
first
f'(x)=
(x-4)(-2x+4)
-2x^2+12x-16
we know that

so therefor maybe
-2x^2=rnx^{n-1}
2=n-1
n=3
rn=-2
3r=-2
r=-2/3
one is

second part
12x
12x=

x^1, 1=n-1
n=2
rn=12
2r=12
r=6

is the second bit
last part
-16
-16x^0=

0=n-1
n=1
rn=-16
1r=-16
r=-16
-16x^1
so therfor f(x)=
17.9/2.38
= 7.5.
Hope this helps & good luck. :)
