Question

Suatu fungsi dinyatakan dengan x ⇒ 1/2 (5-x). jika daerah asalnya { -3,-1,1,3,5}, tentukan bayangannya!





\frac{1}{2}

Answer 1

(-3) = ½(5+3) = 5/2 + 3/2 = 8/2 = 4
(-1) = ½(5+1) = 5/2 + ½ = 6/2 = 3
(1) = ½(5-1) = 5/2 -½ = 4/2 = 2
(3)= ½(5-3) = 5/2 + 1 = 6/2 = 3
(5)= ½(5-5) = 5/2 - 5/2 = 0,2
jadi himp. bay. = {(4),(3),(2),(0,2)}
