Suatu fungsi f (x) =X2-9.tentukan rangenya jika dominannya {-2,-1,0,1,2,3}

domain = {-2,-1,0,1,2,3}
f(x) = x² - 9
range :
f(-2) = (-2)²-9 = 4-9 = -5
f(-1) = (-1)²-9 = 1-9 = -8
f(0) = (0)²-9 = 0-9 = -9
f(1) = (1)²-9 = 1 - 9 = -8
f(2) = (2)²-9 = 4 -9 = -5
f(3) = (3)²-9 = 9 -9 = 0

daerah hasil = {0,-5,-8,-9}

maaf kalo salah
