diketahui f (x) = ax+b.jika f (-1)=5 dan f (-3)= -13,maka f(2) adalah

F(-1) = -1a + b = 5
F(-3) = -3a + b = -13
----------------------------- -
2a = 18
a = 18/2 = 9
-1a + b = 5
-1 . 9 + b = 5
-9 + b = 5
b = 5 + 9 = 14

F(2) = 2.a + b = 2.9 + 14 = 18 + 14 = 32

F(2) = 32


Bingung?? Tanya di komentar yah!

Semoga membantu kakak
