Question

calculate the derivative of f if f(x)=sqrt2x+5/x^3+1

Answer 1

right?
\[f(x)=\frac{\sqrt{2x+5}}{x^3+1}\]

Answer 2

Use
\[\frac{d}{dx}(\frac{u}{v})= \frac{v \frac{d}{dx} (u)-u \frac{d}{dx} (v)}{v^2}\]

Answer 3

do you just take the derivative of what's inside the square root sign?

Answer 4

no, the whole function

Answer 5

your u will be the square root thing and v the x^3+1
