Choose the correct option.
The second derivative of y = x³ - 5x² + x is:
The second derivative of $y = x^3 - 5x^2 + x$ is:
- (a)$10x - 5$
- (b)$6x - 10$
- (c)$3x^2 - 10x$
- (d)$3x^2 - 10x + 1$
Answer
Answer
Correct option: (b)
Answer: (b) $6x - 10$
$\frac{dy}{dx}=3x^2-10x+1$
Hence $\frac{d^2y}{dx^2}=6x-10$.
