    Let S ⊂ R be a non-empty set. For any functions f and g from S into R, define d(f,g) := sup{|f(x)−g(x)| : x∈S}. Is d always a metric on the set F of functions from S into R? Why or why not? What does your answer suggest that we do to find a (useful) subset of functions from S to R on which d is a metric, if F does not work? Give a brief justification for your fix.
