Unit+3+-+Functions

Sophie vs Yash

Yash: A function is a correspondence between two variables in which the input values (domain) can only have one output value (range). However, the output value (range) can have more than one input value (domain).

Sophie: A function is a relationship between 2 sets of number, form the first set (domain), is equal to exactly one value from the second set (range). :)
