Daerah hasil dan fungsi f(x)=x²-3 dgn domain {-3,-2,-1,0,1,2,3} adalah....

Bab Fungsi
Matematika SMP Kelas VII

f(x) = x² - 3

f(-3) = (-3)² - 3
       = 6

f(-2) = (-2)² - 3
       = 1

f(-1) = (-1)² - 3
       = -2

f(0) = 0² - 3
      = -3

f(1) = 1² - 3
      = -2

f(2) = 2² - 3
       = 1

f(3) = 3² - 3
      = 6

Daerah hasil = { -3, -2, 1, 6 }
