Question

F(-3)=-17 dan f(3)=5 hasilnya apa dan jelaskan jalannya

Answer 1

Maaf, yang ditanya f x nya yy????

Answer 2

Misal:
f(x) = ax + b
f(-3) = - 17
- 3a + b = - 17 ... (1)
f(3) = 5
3a + b = 5 ... (2)

eliminasi:
- 3a + b = - 17
3a + b = 5
___________ - 
- 6a = - 22
a = 22/6
= 11/3
b = - 17 + 11 = - 6

f(x) = (11/3)x - 6
