Penyelesaian :

Jika suatu fungsi f(x) = -x² dengan batasan { -4, -3, -2, -1, 0, 1, 2, 3, 4} maka daerah hasil adalah ...

Range (Daerah hasil)

Daerah asal {-4, -3, -2, -1, 0, 1, 2, 3, 4}

f(x) = -x²

f(-4) = -(-4)² = 4² = 4 × 4 = 16

f(-3) = -(-3)² = 3² = 3 × 3 = 9

f(-2) = -(-2)² = 2² = 2 × 2 = 4

f(- 1) = -(- 1)² = 1² = 1 × 1 = 1

f(0) = -(0)² = -0² = -0 × -0 = 0

f(1) = -(1)² = -1² = -1 × -1 = 1

f(2) = -(2)² = -2² = -2 × -2 = 4

f(3) = -(3)² = -3² = -3 × -3 = 9

f(4) = -(4)² = -4² = -4 × -4 = 16

Maka daerah hasil atau Range adalah Daerah hasil = {16, 9, 4, 1, 0, 1, 4, 9, 16}
