5f(×)+4g(×)= Jawaban nyah gimna

Jawaban:

F(x) = 5x^3 – 4x^2 + 3x – 2

5f(4) = 5[5(4^3) – 4(4^2) + 3(4) – 2]

5f(4) = 5[5(64) – 4(16) + 12 – 2]

5f(4) = 5[320 – 64 + 12 – 2]

5f(4) = 5(266)

5f(4) = 1330

4f(3) = 4[5(3^3) – 4(3^2) + 3(3) – 2]

4f(3) = 4[5(27) – 4(9) + 9 – 2]

4f(3) = 4[135 – 36 + 9 – 2)

4f(3) = 4(106)

4f(3) = 424

5f(4) – 4f(3)

= 1330 – 424

= 906
