Practice problem
Find the derivative of the function using the definition of derivative. f(x)=2−x2+xf(x)=\frac{2-x}{2+x}f(x)=2+x2−x
−4(x+2)2-\frac{4}{(x+2)^2}−(x+2)24
2(x+2)\frac{2}{(x+2)}(x+2)2
−x(x+2)2-\frac{x}{(x+2)^2}−(x+2)2x
−1(2x)2-\frac{1}{(2x)^2}−(2x)21
Type a concept, like “slope” or “photosynthesis”.
