If y = 4×3 – 2×2 + x, find (frac{delta y}{delta x})

If y = 4x3 – 2x2 + x, find (frac{delta y}{delta x})
  • A.
    8x2 – 2x + 1
  • B.
    8x2 – 4x + 1
  • C.
    12x2 – 2x + 1
  • D.
    12x2 – 4x + 1
Correct Answer: Option D
Explanation

If y = 4x3 – 2x2 + x, then;
(frac{delta y}{delta x}) = 3(4x2) – 2(2x) + 1
= 12x2 – 4x + 1
