If y = x2 – \(\frac{1}{x}\), find \(\frac{\delta y}{\delta x}\)
- 2x - \(\frac{1}{x^2}\)
- 2x + x2
- 2x - x2
-
2x + \(\frac{1}{x^2}\)
The correct answer is: D
Explanation
y = x2 - \(\frac{1}{x}\)y = x2 - x-1
\(\frac{\delta y}{\delta x}\) = 2x + x-2
\(\frac{\delta y}{\delta x}\) = 2x + \(\frac{1}{x^2}\)
