Answer:
The given function
was replaced with
then the value of k is -3
that is k=-3.
Step-by-step explanation:
The given function is
and when x=x+k then 
Now to find the value of k:
Put x=x+k in the function f(x)
Now comparing equations (2) and (3) we get







Therefore k=-3
Therefore the given function
was replaced with
then the value of k is -3
that is k=-3.
Answer:
x=-1/4+i*sqrt(47)/4 and x=x=-1/4-i*sqrt(47)/4
Step-by-step explanation:
Using quadratic formula, x=(-1±sqrt(1-48))/4.
x=-1/4+i*sqrt(47)/4 and x=x=-1/4-i*sqrt(47)/4
