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 !!!!
If this paper dosent help u solve it on Your own i can walk u through it
Answer:
x = 7
Step-by-step explanation:
the 2 is doubled so the 3.5 has to be doubled as well
X intercept: (-4,0)
y intercept: (0,1/2)
x-intercept is when y = 0
-x+8(0)=4
-x+0=4
x=-4
y-intercept is when x = 0
-(0)+8y=4
8y=4
y=4/8=1/2
