Homeworkk, math help please?

here it goes kiddo

y=-x2+4x-6

-2x+4x=2x

rewrite:

y=2x-6

now here is how it goes:

2x is actually equal to :2x

----------------------->... --------------

..................................... 1x

so go to the graph and put a pencil in the (0,0) then move to (2,1)

and move down 6 so it should be (2,-5)

PUT THAT IN A GRAPH PAPER AND COPY EQUATION SO TEACHER HAVE "PROOF" THAT YOU DID IT....WHEN I ACTUALLY DID IT 4 U

y = -x^2 + 4x - 6 is a parabola

The x-coordinate of the vertex is given by x = -b/2a

So the x-coordinate of the vertex is -4/(-2) = 2

btw ... If you had to give the y-coordinate, just subs x = 2 into the equation to find y.

put it into your calculator and then press graph. find the vertex (x,y).
