look for the interceptions add these and divide it by 2 (that's the x vertex) for the yvertex you just have to fill in the x(vertex) however you can also use the formula -(b/2a)
The formula for the vertex form is: f(x) = a(x-h)^2 + k Where (h,k) is the vertex. The equation also tells us the direction of opening, which is the a value, in this case opens up because a is...
The vertex form of a quatdratic equation (otherwise called the graphing form) is y=a(x-h)2+kFor those of you who don't know what 'h', 'a', and 'k' are, they are parameters. The negative sign in front...
