$derivdef\left(6d+6\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of 4d+62d using the definition. Combining like terms 4d and 2d. Find the derivative of 6d+6 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 6d+6. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term -1 by each term of the polynomial \left(6d+6\right). Add the values 6 and -6.
