How do i plot this graphic quadratic equation y=x^2-8x+12.I have tried but i end up failing.Please help me and explain in detail plz help out.

Answer 1

there are lots of online graphing sites. Just type your equation in at wolframalpha.com

It will show you all you want to know about that graph.

Though I fail to see how you could have tried and failed. Can you not plot points and connect them, knowing that this is a parabola?

Answer 2

x^2-8x+12 = 0. 12 = -2*(-6). -2 + (-6) = = -8 = B.
(x-2)(x-6) = 0
x-2 = 0, X = 2.
x-6 = 0, X = 6.
roots: (2, 0), (6, 0).
Y-int. = (0,12). (8,12).

h = -B/2A = 8/2 = 4.
k = 4^2-8*4 + 12 = -4.
V(h, k) = V(4, -4).

Graph: (0,12), (2,0), V(4,-4), (6,0), (8,12).
