$derivdef\left(x-1\cdot 4\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of (x-4)^2=x-2^2 using the definition. Calculate the power 2^2. Multiply -1 times 4. Find the derivative of x-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 x-4. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term -1 by each term of the polynomial \left(x-4\right).
