Find frac dy dx if y frac 2 3 X3 - frac 4 x - JAMB Mathematics 2016 Question
Find \(\frac{dy}{dx}\), if y = \(\frac{2}{3}\) X3 - \(\frac{4}{x}\)
A
3x2 - \(\frac{4}{x}\)
B
2x2 +\(\frac{4}{x^2}\)
C
3x2 + \(\frac{4}{x^2}\)
D
2x2 - \(\frac{4}{x}\)
correct option: b
y = \(\frac{2}{3}\)x3 - \(\frac{4}{x}\)
\(\frac{dy}{dx}\) = 2x2 - Lx-2 = 2x2 + \(\frac{4}{x^2}\)
\(\frac{dy}{dx}\) = 2x2 - Lx-2 = 2x2 + \(\frac{4}{x^2}\)
