Question 145432This question is from textbook Intermediate Algebra
: Find the domain and write in interval notation
f(x)= 2x+1/3x+5
it looks like a fraction: f(x)= 2x+1 "over" 3x+5
I have an answer sheet but it doesn't help because I don't understand how to work the problem to find the answer...any help would be greatly appreciated!

Find the domain and write in interval notation
f(x)= (2x+1)/(3x+5)
-------
Domain: The only restriction on "x" is that the
denominator of the fraction must not be zero.
3x+5 = 0 when x = -5/3
Therefore the domain is "All Real Numbers except x = -5/3".
Interval Notation: (-inf,-5/3)U(-5/3,+inf)
