$derivdef\left(4-x-8\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of 3x=4-(x+8) using the definition. Simplify the product -(x+8). Subtract the values 4 and -8. Find the derivative of -4-x 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-x. 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+h\right).
