thank you!

1. Partial and Total Functions For each of the following function definitions, give the graph of the function. (See the text for a definition of graph a set of ordered pairs, NOT a picture!) Say whether this is a partial function or a total function on the integers. If the function is partial, say where the function is defined and undefined. We will use the symbols x/0 to indicate an undefined quantity For example, the graph of f (x) = if x > 0 then x + 2 else x/0 is the set of ordered pairs x,z +2) | >0. This is a partial function. It is defined on all integers greater than 0 and undefined on integers less than or equal to 0 Functions (a) f(x) -if x 2 3 then x 5 else x/0 (b) f (x) = if x
