If i understand the machine correctly and -3 is x and 8 is the final answer, f(x)=x+11
Answer: x = 1 ± i
Step-by-step explanation:
Solving the quadratic equation using the quadratic formula:
x =
or
From the question :
a = 1
b = -2
c = 2
substituting inside the formula
X =
or

x =
or 
x =
or 
Recall ;
can be written as
X
, and
= i
Substituting this
x =
or 
simplifying, we have
x = 1 + i or 1 - i
Answer:
D
Step-by-step explanation:
