Question

Find the coordinates of the vertex for the parabola whose equation is
f(x) = -4x2 + 8x - 4

Answer 1

for your x coordinate use x=-b/2a

Answer 2

then sub that to your y for the y coordinate

Answer 3

lol its multiple choice my bad haha

(-2,36)

(-1,-16)

(2,-12)

(1,0)

Answer 4

.f(x) = y=-4x2 + 8x - 4 , a=-4, b=8, c=-4
x=-b/2a
==-8/2(-4)=__? then sub this to y

Answer 5

?

Answer 6

what did you get on youR x?

Answer 7

idk....just tell me the answer please. i gave you the multiple choices dude lol i really dont have time to sit here and figure it out .

Answer 8

.f(x) = y=-4x2 + 8x - 4 , a=-4, b=8, c=-4

x=-b/2a

x=-8/2(-4)=__? then sub this to y......... :D
x=1 yes or no? sub this to f(1)=y=__ ?

hmm i got into trouble of just giving answers many times ...LOL.... :D
the x is there already just find y__? ...:D
