Is that the "greatest integer function," y=[x]?  Did part of your illlustration of the function get cut off from the top?

mathmale · Answer

If so, can you graph y=[x]?

Using the pattern visible in this graph, can you determine the value of your function when x is just less than 7?  when x is just a bit greater than 7?

mathmale · Answer

For example, x=6.5 is just below x=7.  What is the value of f(x) when x=6.5?

What is the value of {6.5}?  

Please note that the function changes sign at x=7.
