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 general form of a quadratic equation is y = ax2 + bx + c, where a, b and c are real constants and a ≠ 0. If a = 0 then it is not a quadratic! There are two ways of classifying the forms. "CUP...
