Question

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

Answer 1

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.
