Answer 1

f(x) = 17x + 15x - 4x³

f(7) = 17(7) + 15(7) - 4(7)³

f(7) = 119 + 105 - 4(7.7.7)

f(7) = 224 - 4(343)

f(7) = 224 - 1.372

f(7) = ( -1.148 )

Answer 2

Jawaban:

Penyelesaian :

• f(x) = 17x + 15x - 4x³

• f(7) = 17(7) + 15(7) - 4(7)³

• f(7) = ( 17 × 7 ) + ( 15 × 7 ) - 4(7³)

• f(7) = 119 + 105 - 4( 7 × 7 × 7 )

• f(7) = 119 + 105 - 4( 49 × 7 )

• f(7) = 119 + 105 - 4(343)

• f(7) = 119 + 105 - ( 4 × 343 )

• f(7) = 119 + 105 - 1.372

• f(7) = ( 119 + 105 ) - 1.372

• f(7) = 224 - 1.372

• f(7) = -1.148
