The vertex form of a quadratic equation is f(x)=a(x−h)2+k. Vertex form is used to easily identify the vertex, (h,k). The standard form of a quadratic equation is f(x)=ax2+bx+c. Standard form is used to easily identify the y-intercept of the function, (0,c). It is ...
The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter

Find the Vertex y=-x^2+4y=-x^2+4 相关知识点: 试题来源: 解析 Rewrite the equation in vertex form.y=-(x+0)^2+4Use the vertex form, y=a(x-h)^2+k, to determine the values of a, h, and k.a=-1h=0k=4Find the vertex(h,k).(0,4)∴ ...
x2=−4ayComparing this with the given equation x2=−16y, we can identify that:4a=16⟹a=4 Step 2: Find the vertexThe vertex of the parabola in the standard form x2=−4ay is at the origin (0, 0). Therefore, the vertex is:Vertex=(0,0) Step 3: Find the focusThe focus...
(双根式):y=a(x-b)(x-c) 如果二次方程遇到的是Factored Form的话,利用从factored form中得出来的两个zero的中值可以算出顶点横坐标,然后把这个横坐标带回到方程中求出的y值就是顶点纵坐标。 e.g. y=9(x+2)(x-4),从两个factor中可以看出抛物线...
