§ HELP PLS 10 POINTS PLEASE ANSWER BOTH QUESTIONS

okay let me try to do this

Step-by-step explanation:

so the first on is the graph on the top right, because the others wouldn't work. They wouldn't work because one is curved, one is 4 different lines, and one is not a straight line. so the top right is the function.
