Step 1

Halo semuanya! Mari kita cari invers dari fungsi f x sama dengan satu dikurang dua x.

Menentukan Invers Fungsi

2
Step 2

Langkah pertama dalam mencari invers adalah memisalkan f x sebagai variabel y.

$$f(x) = 1 - 2x$$
$$y = 1 - 2x$$
3
Step 3

Tujuan kita sekarang adalah mengisolasi variabel x ke satu sisi. Mari kita pindahkan satu ke ruas kiri.

4
Step 4

Sekarang, kita ingin menghilangkan tanda negatif pada negatif dua x. Mari kita kalikan kedua ruas dengan negatif satu.

5
Step 5

Kita distribusikan tanda negatifnya, sehingga persamaannya menjadi satu dikurang y sama dengan dua x.
