$derivdef\left(3x+x\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of x+2xx using the definition. Combining like terms x and 2x. Combining like terms 3x and x. Find the derivative of 4x 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 4x. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term 4 by each term of the polynomial \left(x+h\right).
