Question

Is the relation a function?
{(14,9), (15,8), (8, 7), (1,9), (15, 2)

Answer 1

No the relation is not a function

Explanation:

This is because there are 2 x factors that have the value of 15. (15,8) and (15,2)

in order to make this a function you would have to change the one of the x factor of the 2 ratios:

(15,8) and (15,2)
