Answer:
Hello,
Step-by-step explanation:
Roots are -2 and 4
y=k*(x+2)(x-4)
Vertex = (1,-9) is a point of the parabola
-9=k*(1+2)(1-4) ==> k=1
Equation of the parabola is y=(x+2)(x-4)
But you don' t have given the graphs !!!!
2/3-> 4/6
1/2-> 3/6
Subtract
1/6
2/5-> 16/40
1/8-> 5/40
Subtract
11/40
Number 3.
opens up
vertex (1,2)
idk maybe because it is on the right side. its positive
number 4.
opens up as well
Vertex (-2,0)
no because it is negative and on the left. Idk just a guess for this one
