Practice problem
Find the derivative of f(x)f(x)f(x). f(x)=x4−2x2xxf(x)=\frac{x^4-2x^2\sqrt x}{x}f(x)=xx4−2x2x
f′(x)=10x2−4xf'(x)=10x^2-4\sqrt xf′(x)=10x2−4x
f′(x)=4x3−5xxf'(x)=4x^3-5x\sqrt xf′(x)=4x3−5xx
f′(x)=5x2−7xf'(x)=5x^2-7\sqrt xf′(x)=5x2−7x
f′(x)=3(x2−x)f'(x)=3(x^2-\sqrt x)f′(x)=3(x2−x)
Type a concept, like “slope” or “photosynthesis”.
