Question

Diketahui f:(x):2x-1 dengan daerah asal (0,1,2,3,4)

Answer 1

F(x) = 2x - 1
domain = {0,1,2,3,4}
f(0) = 2 . 0 - 1 = 0 - 1 = -1
f(1) = 2 . 1 - 1 = 2 - 1 = 1
f(2) = 2 . 2 - 1 = 4 - 1 = 3
f(3) = 2 . 3 - 1 = 6 - 1 = 5
f(4) = 2 . 4 - 1 = 8 - 1 = 7
range atau daerah hasil = {-1, 1, 3, 5, 7}
jadikan jawaban terbaik ya :-)
