Draw a mapping diagram for the given
relation. Is it a function?
{(3,-1), (6, 4), (8,4)}?

It is not technically a function.  This is because by definition, a function should produce a distinct output value for every unique input value.  In this case 8 and 6 both give you four, so it is not a function.

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes
