Ekstrapolasi is a method for estimating a variable value that exceeds the value of an interval (or 2 points on a line) based on the relationship between the variables. It is the extension of data outside available data, but still follows the trend pattern of available data. Extrapolation is estimating the value of a function outside the available data points, but does not change the number of variables. Extrapolation is a method to determine or estimate a value that is outside the interval or two points on a line.

2. Apa itu Ekstrapolasi ?
Ekstrapolasi merupakan suatu metode untuk memeperkirakan suatu nilai variabel yang
melampaui nilai interval (atau 2 titik yang segaris) berdasarkan hubungan antara
variabelnya. Perluasan data di luar data yang tersedia, tetapi tetap mengikuti pola
kecenderungan data yang tersedia. Ekstrapolasi adalah memperkirakan nilai fungsi di
luar titik data yang tersedia, tetapi tidak mengubah jumlah variabel. Ekstrapolasi
merupakan metode untuk menentukan atau memperkirakan suatu nilai yang berada di
luar interval atau dua titik yang segaris.

Berikut ini contoh soal yang berkaitan dengan
ekstrapolasi:
Sebuah mobil dapat menempuh jarak 10
kilometer dengan 1 liter bensin, dan 20 kilometer
dengan 2 liter bensin. berapakah jarak yang
ditempuh mobil tersebut jika mobil tersebut
menggunakan 4 liter bensin ?

5. Berikut ini pembahasannya
Misalkan jarak (km) adalah x dan bensin adalah y maka,
• 10 kilometer =x1
• 20 kilometer=x2
• 1 liter bensin =y1
• 2 liter bensin = y2
• 4 liter bensin = y
yang dicari adalah jarak pada saat
mobil menggunakan 4 liter bensin
dalam hal ini misalkan x
sehingga
𝑦−𝑦1
𝑦2−𝑦1
=
𝑥−𝑥1
𝑥2−𝑥1
4 𝑙𝑖𝑡𝑒𝑟−1 𝑙𝑖𝑡𝑒𝑟
2 𝑙𝑖𝑡𝑒𝑟−1 𝑙𝑖𝑡𝑒𝑟
=
𝑥−10 𝑘𝑚
20−10 𝑘𝑚
3 𝑙𝑖𝑡𝑒𝑟
1 𝑙𝑖𝑡𝑒𝑟
=
𝑥−10 𝑘𝑚
10 𝑘𝑚
30 km = (x -10 km)
x = 40 km
