High School Where is the vertex of the parabola f(x) = x^2 - 5x + 6?
See, there is an equation which is f(x) = x^2 - 5x + 6. On the points 2 and 3 of the x axis, they reach 0. So where is the vertex? I'm guessing its -.25, but just to make sure i had to ask. Well, our class seemed to have a lot of it and our teacher, Ms. Knudsvig, didn't know.- darkfire313

Finding Parabola Equation with Vertex and X-Intercept
0 = a921600 + 1920. Huh. It means a is -1/480. Wow. Amazing. And how come I am editting this after a year?- darkfire313

Finding Parabola Equation with Vertex and X-Intercept
Ever heard of the line of symmetry? A parabola has one in the middle. 1920 - 960 = 960 1920 + 960 = 2780 There! Two X-intercepts!- darkfire313
