Consider the following relation: {(1,12), (3,8), (3,11), (6,9), (7,11)} Which ordered pair could be removed so that the relation is a function.

Either (3,8) or (3,11) should be removed

Step-by-step explanation:

Because a function can only have one point per x-value, there cannot be any repeating x-values in ordered pairs the function.

Therefore, because the ordered pairs (3,8) and (3,11) both share "3" as their x-value, one of them has to be removed from the list of ordered pairs to make the relation a function.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
