You will graph the function, f(x) = greatest integer function (x/2-3). Make one graph using all the details below.

 

A. Make a table of values for the function. The table should have at least five values including the x-values already listed below.

B. Using the table, plot a graph of the function. 

 

C. Restrict your graph domain to the interval [0,4] or 0 ≤ x ≤ 4. Make sure your graph correctly displays all required hollow/solid dots.

This is also known as a "floor" function......

 

x       0      1/2       1      1.5      2      2.5    3       3.5     4

f(x)   -3      -3       -3      -3       -2     -2      -2       -2     -1

 

 

B.   Probably  can just look at this graph :  https://www.desmos.com/calculator/ghq8u1vhs0

 

The "holes" in the graph occur at the right end of the little "dashes"

Am I able to make the table

x    0   1/2   1   1.5   2   2.5   3   3.5   4

f(x) 1    1    1     1     2     2     2     2   3

 

And then for the graph it can be floor(x/2+1){0 ≤ x ≤ 4}

 

I have to hand plot a graph of the function and the area given to me does not expand past -1.
