Question

Diketahui fungsi f : x -> (x² - 3x+2) dengan daerah asal D={-2,-1,0,1,2}. Tentukan wilayah hasil nya.

Answer 1

F(x) = (x² - 3x + 2) f(-2) = (-2)² - 3(-2) + 2 = 4 + 6 + 2 = 12 f(-1) = (-1)² - 3(-1) + 2 = 1 + 3 + 2 = 6 f(0) = (0)² - 3(0) + 2 = 0 - 0 + 2 = 2 f(1) = (1)² - 3(1) + 2 = 1 - 3 + 2 = 0 f(2) = (2)² - 3(2) + 2 = 4 - 6 + 2 = 0 Nb: maaf kalo salah :)
