F:x= -x3+1 dengan daerah asal {x/1<_x<_4,xbilangan bulat} daerah hasil fungsi f adalah

[tex]f(x)=-x^{3}+1 \\ [/tex]

Daerah Asal = {1, 2, 3, 4}

Daerah Hasil = ?
f(1) = - (1)³ + 1 = - 1 + 1 = 0
f(2) = - (2)³ + 1 = - 8 + 1 = - 7
f(3) = - (3)³ + 1 = - 27 + 1 = - 26
f(4) = - (4)³ + 1 = - 64 + 1 = - 63

Daerah Hasil = {0, -7, -26, -63}  

f (x) = -x^3 + 1
f (1) = - (1)^3 + 1= -1 + 1 = 0
f (2) = - (2)^3 + 1 = -8 + 1 = -7
f (3) = -(3)^3 + 1 = -27 + 1 = -26
f (4) = -(4)^3 + 1 = -64 + 1 = -63
Range = 0, -7, -26, -63
