For each of the following statements, determine whether it is
true or false and justify your answer.
a. If the function f + g: IR --> IR is continuous, then the
functions f :IR --> IR and g :IR --> IR also are
continuous.
b. If the function f^2 : IR --> R is continuous, then so is the
function f :R --> IR.
c. If the functions f + g: IR and g: IR --> IR are continuous,
then so is the function f :IR --> IR.
d. Every function f: N --> IR is continuous, where N denotes the
set of natural numbers.
