+1713 Math TOPIC(and apparently problem) question...
Right, so my question is how do you get the domain of a function?
I know this differs from the traditional one problem, but I think that giving me help on a whole topic will be better, so I can solve it on my own. Thank you in advance to anyone who helps
Deep Thanks, 😀😃😄😁😊😇😌😋😜😎

EDIT:
The part I am having trouble understanding is how would you do it to a polynomial fraction function...
Like how would you find the domains such things?
EDIT(again):
How would you solve for the domain
\(f(x)=\frac{x^2-4}{x-4}\)
Just help me through the steps plsssssssssss
+118687 Assuming your function is of the form y=f(x)
then the domain is just the set of all possible x values.
With a normal polynomial that is all real x
I am not sure what you mean by a poynomial fraction function.
I suppose if there is an x on the bottom of a fraction then there will be restrictions because it is not possible to divide bt 0.
+1713 that was actually my hw question and I don't know how to solve it... Can you help?
+118687 Well the bdenominator cannot be 0 so x cannot be 4. x can be anything else.
So the domain is \(x \in Real \;\;\;where \;\;x\ne4\)
This can be written in a number of formats but they all mean the same.
The actual fuction is f(x)=x+4 where x not equal 4
It is a straight line with a hole at (4,8)
