Diketahui :
- x = 10
Ditanya :
- f(x) = 7x + 12x² – x × x + x/2 = ??
Dijawab :
- f(x) = 7x + 12x² – x × x + x/2
- f(10) = 7(10) + 12(10²) – 10 x 10 + 10/2
- f(10) = ( 7 x 10 ) + ( 12 x 100 ) – ( 10 x 10 ) + 10/2
- f(10) = ( 70 ) + ( 1.200 ) – ( 100 ) + 10/2
- f(10) = 1.270 – 100 + 5
- f(10) = 1.170 + 5
- f(10) = 1.175
- f(10) = 1.175
<< Kesimpulan >>
- f(x) = 7x + 12x² – x × x + x/2
- f(10) = 1.175
