Which of the following is/are true?

I. The derivative of

y=2 x-\frac{3}{4}

2.

II. The derivative of

y=\left(5 x^3+3 x-1\right)(x-1)

20 x^3+15 x^2+6 x-4

View answer and explanation

Correct option: B

Only I is true

Option B is correct because only statement I is true. The derivative of y=2x - 3/4 is 2, while the derivative of y=(5x³+3x-1)(x-1) is 20x³ - 15x² + 6x - 4, not 20x³+15x²+6x-4.
