Question 864225: I really need help with this quadratic equation. I have a project and my teacher doesn't explain the information needed. The equation is: x^2-14x+24. I have to graph it and find the following: roots, y-intercept, axis of symetry, and vertex. I don't understand any of it. Please help!

Hi
Go with what You know first
x^2 - 14x + y-intercept is 24 (when x = 0)
(x-12)(x-2) = , Factoring Gives Up the roots: x = 2, 12
As to the Vertex and axis of symmetry of the parabola the Eq represents:
complete the Square
x^2-14x+24 = (x-7)^2 -49 +24 =
V(7, -25)
axis of Symmetry x = 7 (vertical Line through the Vertex)
