Question 348550: I am working on Solving Compound Inequalities
The problem I'm working on is as follows:
Solve the compound inequality, if possible. Graph the solution set (if one exists) and write it using interval notation:
 or 
I've solved both linear equations and have what follows:
 or 
My problem is the interval notation. I graphed the answers & I don't understand why the answer in the back of the book is (-infinity, 1).
They intersect at -9/2. I thought the answer would be no solution.
The only thing I can think of, is that if the answer intersects and goes both ways, the answer is (-infinity, infinity), but since this one is only going negative, it's (-infinity, 1).
Thank you for your time!
