Step-by-step explanation:
at -3,y=-2(-3)²+4=-14
at -2,y=-2(-2)²+4=-4
at -1,y=-2(-1)²+4=2
at 0,y=-2(0)²+4=4
at 1,y=-2(1)²+4=2
at 2,y=-2(2)²+4=-4
at 3,y=-2(3)²+4=-14
Answer:
you need to do in table like I show you
so you need to substitute your y given in the table given and sub in to the equation given which is y = 2x square+4
