Bantu yaa :)
Fungsi f:(x) → 3x -5
x (a) himpunan {(-3), (-2), (-1), (0), (1), (2)}
Tentukan!
a. Range fungsi
b. Himpunan Pasangan Berurutan fungsi
c. Diagram panah fungsi

Answer 1

F(x) = 3x -5
 f(-3) = 3.-3 -5 = -9-5= -14
 f(-2)= 3.-2 -5 = -6-5= -11
 f(-1) = 3.-1 -5 = -3-5 = -8
 f(0) = 3.0 -5 = 0-5 = -5
 f(1)= 3.1 -5 = 3-5 = -2
 f(2)= 3.2 -5 = 6-5 =1
a.  { -14, -11, -8 , -5, -2, 1 }
b. { (-3,-14) (-2,-11), (-1, -8) (0,-5) ( 1,-2) (2, 1) }
