the equation is...

I first approached this problem by solving for x in both and

In both cases, I ended up with an inequality that still had x on one side and an expression that is probably equivalent to the original expression on the other side. This didn't really tell me anything.

One thing that occurred to me was that it may be true in this case that y=x was one of the barriers.

So i graphed myself (without the use of a graphing calculator). the parent function is . so y=|3x-4| is y=|x| compressed horizontally by a factor of (1/3) and moved to the right 4 units. I do not know how to graph with latex (or if it is even possible), so maybe you could quickly graph this yourself with pen and paper, or just imagine it. basically its a narrower "V" shape moved over to the right 4 units. After graphing this, I then graphed y=x on the same plot and figured that the solution set existed between the two functions (i.e. < y=x & > y=|3x-4|).

But then I graphed the two equations using a graphing calculator and saw that my graph of y=|3x-4| looked different from the graphing calculator's graph of the same function. Furthermore, the back of the book shows that the solution set is between and including 1 and 2, which is confirmed when looking at the graphing calculators graphs of y=x and y=|3x-4|.

So i'm like, did i graph y=|3x-4| wrong? but i don't see how i did. Basically, the only difference between my graph of the function and the graphing calculator's is that it seems the calculator moved the graph over (4/3) units to the right and i moved the graph over 4 units to the right.

This is the longest post, i just thought it would be helpful for you to know how i was thinking about this problem. So, how would i solve this inequality algebraically and why is my graph wrong?
