The question format is not clear.
Quick answer: log of a negative is not permitted so it is a no no to
Explanation:
NOT MEANT TO BE:
This would be very different!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So we have:
Set:
This is the equation of a strait line
So for this condition we have:
domain (input)
range (output)
However; as there is no 'excluded values' in this it is a little disconcerting that mention is made of an asymptote.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So perhaps the question is meant to be:
Set
Converting this to log base 10 we have
Now this is different as you do have excluded values, in that, from
So we have permitted value of
As
As
so
When
See explanation.
Explanation:
The range is the set of all numbers for which the formula is defined.
In this example we have a
#x+4>0 #
So the domain is:
The
The asymptote is
The graph is:
graph{ log(x+4) - 3 [-6, 30, -17.26, 5.25]}
