diketahui rumus fungsi f(x) = ax+b .jika f(6) =13 dan f(-2)=-11 , maka f(7) adalah

Semoga membantu yaa..

F(x) = ax + b
F(6) = 6a + b = 13
F(-2) = -2a + b = -11
ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ ㅡ
8a = 24
a = 24 ÷ 8
a = 3

a = 3 ㅡ> 6a + b = 13
6(3) + b = 13
18 + b = 13
b = 13 - 18
b = -5

F(7) = ax + b
F(7) = 3(7) + (-5)
F(7) = 21 + (-5)
F(7) = 16

Maaf kalau salah.
