Vertex Form

The vertex form of a quadratic function is $f(x)=a(x-h)^{2}+k$, where $(h,k)$ is the vertex, the turning point of the parabola. The value of $a$ controls the width and direction, while $h$ and $k$ shift the graph horizontally and vertically.

It shows the maximum or minimum at a glance.

You meet Vertex Form in the Quadratic Functions chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.

Our teachers make sure a student can not only recite what Vertex Form means but use it fluently in a full solution.

Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Vertex Form (EN) · Bentuk Verteks (BM) · 顶点式 (中文)
