Diketahui :
f(x) = 17x - 8x + 1.945
Ditanya :
f(77) = ?
Jawab :
f(77) = 17(77) - 8(77) + 1.945
f(77) = ( 17 × 77 ) - 8(77) + 1.945
f(77) = 1.309 - 8(77) + 1.945
f(77) = 1.309 - ( 8 × 77 ) + 1.945
f(77) = 1.309 - 616 + 1.945
f(77) = ( 1.309 - 616 ) + 1.945
f(77) = 693 + 1.945
f(77) = 2.638
f(x) = 17x - 8x + 1945
f(77) = 17(77) - 8(77) + 1945
f(77) = 1309 - 616 + 1945
f(77) = 693 + 1945
