f(x) = x³ + x³ - x
f(25) = ...​

Diketahui :

f(x) = x³ + x³ - x

--

Ditanya :

nilai dari f(25) = ...

--

Jawab :

f(x) = x³ + x³ - x

f(25) = 25³ + 25³ - 25

f(25) = ( 25 × 25 × 25 ) + 25³ - 25

f(25) = ( 625 × 25 ) + 25³ - 25

f(25) = 15.625 + ( 25 × 25 × 25 ) - 25

f(25) = 15.625 + ( 625 × 25 ) - 25

f(25) = 15.625 + 15.625 - 25

f(25) = 15.625 + 15.600

f(25) = 31.225
