Object and Image

In a function $f$, the image is the output value that a particular input produces, written $f(x)$. If $f(3)=7$, then $7$ is the image of the object $3$.

Finding an image means substituting a value; finding the object means solving $f(x)=$ that value.

You meet Object and Image in the 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 Object and Image 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: Object and Image (EN) · Objek dan Imej (BM) · 原像与像 (中文)
