It's the factor theorem.
P(-4)
Equal to 0
Answer:
or 
Step-by-step explanation:
By definition the function
has a domain of
.
Since the function is not defined for the values of x negative or equal to zero.
The range of this function is all the real numbers.
Since
when
and
when 
In this case we have the function 
Therefore since the log function is squared then its range is now 
Photomath is useful for these kinds of problems
