If you type the equation into y1 on your calculator and use the table graph you get coordinates that you can graph. ( 0,-9 ) ( 1,-6 ) ( 2, -3 ) ( 3 , 0 ) ( 4, 3 ) ( 5 , 6 ) ( 6 , 9 ), just graph those and that should answer your question :)
Answer:
i think is the second one
Hello :
2x²+4x-5 = <span>a(x-h)2+k =a(x²-2xh+h²)+k
</span>2x²+4x-5 = ax²-2ahx +ah² +k
a=2.....(1)
-2ah = 4.....(2)
ah²+k=-5...(3)
in (2) : -4h=4 h=-1
in(3) : 2(-1)²+k=-5 k = -7
conclusion : 2x²+4x-5 = 2(x+1)²-7
<span>the vertex is : A(-1,-7)</span>
Answer:2 and 1/2 x
