fungsi f(x)=ax + b jika f(6)= -8 dan f(8)=-14 hitunglah f(-2)!

f(x) → ax + b
f(6) → 6a + b = -8
f(8) → 8a + b = -14
_________ -
-2a = 6
a = 6 / -2
a = -3

f(6) → 6a + b = -8
6 × -3 + b = -8
-18 + b = -8
b = -8 + 18
b = 10

Maka, f(-2) → ax + b
= (-3×-2) + 10
= 6 + 10
= 16

Smoga membantu, maaf klu salah, jdkn jwbn tercerdas y;)
