We calculated f ( x ) and g ( x ) at specific points, finding that they equal each other at x = 2 . Then we analyzed a given relation to determine it has a defined domain and range, confirming it is a function. Finally, we discussed graphing the function f ( x ) = ∣ x + 2∣ and simplifying fractions in a given expression.

•°• Perbandingan usia Ani dan Budi adalah 3 : 5. Jika usia adalah 30 tahun, maka, usia Ani adalah 18 tahun.[tex] \\ \\ [/tex]Penjelasan dengan langkah-langkah:Perbandingan = 3 : 5 → 3/5Usia Budi = 30 tahun Usia Ani = x[tex] \: [/tex]Ani/Budi = Perbandingan x/30 tahun = 3/5x × 5 = 30 × 35x = 90x = 90/5x = 18 tahun[tex] \: [/tex]•°• Jadi, usia Ani adalah 18 tahun.[tex]~[/tex][tex]__________________________________________________________________________________________[/tex][tex] \\ \\ [/tex] [tex]\blue{\boxed{\colorbox{skyblue}{\rm{- AvR}}}}[/tex]

DiketahuiPerbandingan umur 3 : 5DitanyaUmur ani jika umur budi 30 tahunDijawab[tex] = 30 \div 5 \times 3 \\ = 6 \times 3 \\ = 18[/tex]KesimpulanMaka umur ani ialah 18 Tahun.
