diketahui g:x -> x pangkat 2 -5x+4 dengan domain (-2,-1,0,1,2) maka daerah hasilnya adalah....tolong di jawab pakai caranya terima kasih

g(x) = x² - 5x + 4
g(-2) = -2² - 5.-2 + 4
= 4 + 10 + 4 = 18
g(-1) = -1² - 5.-1 + 4
= 1 + 5 + 4 = 10
g(0) = 0² - 5.0 + 4
= 0 - 0 + 4 = 4
g(1) = 1² - 5.1 + 4
= 1 - 5 + 4 = 0
g(2) = 2² - 5.2 + 4
= 4 - 10 + 4 = -2
Maka,
Range (daerah hasil) = {18,10,4,0,-2}
