can you graph the line y=4?
And also y=1?
If so, graph both lines, then erase the parts for the excluded domains. What's left is the graph of f.
Oh, and work on your typing and prooofreading, while you're at it.
enum =5 four=2 three= 1
suppose the function f is defined, for real numbers, as(x) follows
f{4if=0
1ifx=0
graph the function f
