$derivdef\left(3m\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of m+2m using the definition. Combining like terms m and 2m. Find the derivative of 3m 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 3m. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term 3 by each term of the polynomial \left(m+h\right). Simplifying.
