Please jawab+pnjelasan . diketahui rumus suatu fungsi adl f(x) = ax + b . jika nilai f(3) = 8 dan f(-2) = -7 . maka nilai a dan b berturut turut adalah ....

F(3) = 3a + b = 8 f(-2)= -2a + b = -7 _ 5a = 15 a = 3 ambil salah satu 3a + b = 8 3a + 3 = 8 3a = 8 -3 3a = 5 a = 5/3
f(-2)= -2a + b = -7 _
5a = 15
a = 3
ambil salah satu
3a + b = 8
3a + 3 = 8
3a = 8 -3
3a = 5
a = 5/3
f(3) = 3a+b = 8
f(-2) = -2a+b = -7 -
5a = 15
a = 3
-2a+b = -7
-2.3+b = -7
-6 + b = -7
b = -1
⇔ Jadi, a = 3 dan b = -1
