Arelation may assign more than one output value to one of its input values. true or false

Yes, a relation may assign more than one output value to one of its input values.

i.e. the answer is TRUE.

Let A={a,b,c,d} be a set.

Then a relation on a set A is the set or collection of the ordered pair of the type: (x,y) where x and y belongs to the set.

For example--

R={(a,a), (a,b),(a,c),(c,d),(d,a),(d,b)}

is a relation on a set A.

Here the input value may be mapped to more than one element.

for example a is mapped to a , b and c

But for a function each input must be mapped to a single output value.

                    Hence, the given statement is TRUE.

6mm^3 or .6cm^3

factor trees are nice.
