# Exercises 38 and 39 use the following definition: If f : R → R is a function and c is a nonzero real number, the function ( c ⋅ f ) ( x ) R → R is defined by the formula ( c ⋅ f ) ( x ) = c ⋅ ( f ( x ) ) for every real number x . Let f : R → R be a function and c a nonzero real number. If f is onto, is c ⋅ f also onto? Justify your answer.
