1. Is the absolute value of 4-x >14 a disjunction or a conjunction?
Sorry, I do not know those words. Try a Google search.
Now the domain of this is:
4-x > 14 or -(4-x)>14
multiply the left one by -1
*** That means reverse the direction of arrow
x-4 < -14 or x-4 > +14
add 4 to both sides of both
x < -10 or x >18
well the space between x= -10 and x = 18 including the end points is left out of this domain. I suppose that has some meaning in terms of your definitions.
2. If you have a function what is domain?
domain is where the function is defined for the dependent variable.
For example
y = f(x) -1 < x < +1
has a domain between -1 and +1
By the way "range" is the range of y values in that case

Thanks for the help. Does anyone else know if 1 is a disjuncton or conjunction? It's for extra credit before my final.
