Answer:
ttd2
Step-by-step explanation:
1. the vertex form of your function is f(x)= (x+-2)^2+-7
The vertex is at (2,-7)
2. So, the vertex form of your function is f(x)= (x+-7/2)^2 -41/4
The vertex is at (7/2, -41/4)
16
the equation is x = k / y
therefore k = x* y
k = 2*8
k= 16
x/4 = 55
=> x = 55 × 4
=> x = 220
