The function f(x)=(x+4)^2+3 is not one-to-one. Identify a restricted domain that makes the function one-to-one, and find the inv
erse function.
A. restricted domain: x<= -4; f^-1(x)=-4+ sqrt x-3
B. restricted domain: x>=-4; f^-1 (x)=-4 - sqrt x+3
C. restricted domain: x>= -4; f^-1(x) =-4+ sqrt x-3
D. restricted domain: x<= -4; f^-1(x)= -4+ sqrt x+3

Answer:
C.Restricted domain :
, 
Step-by-step explanation:
We are given that a function is not one - to-one.

Suppose 



Hence, 
We know that domain of f(x) is converted into range of
and range of f(x) is converted into domain of
.
Substitute x=3 then we get

Domain of 
Range of 
Domain of f(x)=
Restricted domain :
Hence, restricted domain of f(x) that makes the function one-to-one .
