Verizon
Flat fee of 30 plus 10 equals 40
AT&T
Flat fee of 50 plus 5 equals 55
For them to equal the same
Verizon you need 3 lines which is 30 plus the flat fee of 30 so 60 dollars together
For AT&T
You would need 2 lines of 5 which is 10 plus 50 equals 60
Verizon 3 lines
AT&T 2 lines
Vertical parabola opens down so
(y-k)^2=4P(x-h)
(h,k) is center
P is distance from directix to center and from center to focus (it is 1/2 distance between focus and directix)
-1 to -1/2 is a distance of 1/2
1/2 of 1/2=1/4
P=1/4
so move 1/4 down from -1/2
-3/4
center is (2,-3/4)
so
y+3/4=(x-2)^2
minus 3/4
y=(x-2)^2-3/4
f(x)=(x-2)^2-3/4
you made an error, either the last or first option doesn't have -(x+2)^2
