$derivdef\left(-\frac{20}{5}\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of (-20x^2)/(5x^2) using the definition. Simplify the fraction . Divide -20 by 5. Find the derivative of -4 using the definition. Apply the definition of the derivative: \displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}. The function f(x) is the function we want to differentiate, which is -4. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 4 and -4.
