Answer:
<h2> All but the second</h2><h2> {(8,9),(−2,9),(7,5),(−4,−7)}</h2><h2> {(8,0),(−4,−2),(7,1),(0,0)} </h2><h2> {(−8,3),(−5,−7),(−4,5),(9,3)}</h2>
Step-by-step explanation:
Function means that for each x we get y, and no no x gives two different y-es
{(−5,−7),(−5,4),(−2,−8),(3,5)} for x = -5 we have two different y-es therefore its not function
