Find all x such that \(\lfloor 2x \rfloor = 7\). Give your answer in interval notation.

 

I got (3, 4) at first, but it doesn't seem to be right. I think that the x should be 3 < x < 4, or is there any other value I'm missing? Did I just do my interval notation wrong?

Ahh, never mind. I figured it out, I can't believe I missed this. 

 

I might have some more questions about this topic though...
