Accepted Solution
A:
Answer:The relation is not a functionStep-by-step explanation:∵ {(-7 , -7) , (-7 , -8) , (-1 , 4) , (6 , 5) , (10 , -1)}* The relation is a function if every x-coordinate has only one image of y-coordinate, that means x-coordinate can not appear more than one time in the order pairs of relation.* Ex: {(2 , -3 , (2 , 1)} ⇒ not function because 2 has two values of y -3 and -1 means 2 appears twice in the relation so it's not a function∵ -7 appears twice in the relation (-7 has 2 values of y -7 and -8)∴ The relation is not a function
