Answer:

Hello,

Answer A

Explanation:

Not C since for x=-1,y=(-1-5)²+78= 36+78 ≠ 0

Not D since for x=-1, y= (-1)²+2=1+2=3 ≠ 0
remains A and B
Not B since for x=0, y=0²-1=-1 ≠ -2

Verifying A:
F(-1)=3*(-1)²+(-1)-2=3-3=0 ok
F(0)=3*0²+0-2=-2 ok

F(5)=3*5²+5-2=75+3=78 ok

F(10)=3*10²+10-2=300+8=308 ok
