step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
