Question

Fungsi f didefinisikan dengan rumus f(x)=5-3x dengan daerah asal {-2,-1,0,1,2,3}
A.buatlah tabel dan himpunan pasangan berurutan dari fungsi tersebut
B.gambarlah grafik fungsinya

Answer 1

Pasangannya
-2 = -1
-1 = 2
0 = 5
1 = 2
2 = -1
3 = -4

Answer 2

F(x) = 5 -3x
f(-2) = 5 - 3(-2)
= 5 - 6 = -1f

f(x) = 5 - 3x
f(-1) = 5 - 3(-1)
= 5 + 3 = 8

f(x) = 5 - 3x
f(0) = 5 - 3(0)
= 5 + 0 = 5

f(x) = 5 - 3x
f(1) = 5 - 3(1)
= 5 - 3 = 2

f(x) = 5 - 3x
f(2) = 5 - 3(2)
= 5 -6 = -1

f(x) = 5 - 3x
f(3) = 5 - 3(3)
= 5 - 9 = -4

tabelnya gabisa digambar
