Question

I dont like math please help me:((((((((((((((

Answer 1

y = x²+8x+7

Explanation:

according to the table, we get the point :

(-4, -9) as the vertex and (0, 7) as y-intercept

y = ax²+bx+c

=> the symetry axis :

x = -b/2a = -4

b=-4×2a = 8a

let a=1, => b = 8(1) = 8

y-intercept = (0, c) =(0, 7) => c =7

so, the equation might be :

y = x²+8x+7
