$derivdef\left(1x^3+49-x+28\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of 1x^3+7^2-x+28 using the definition. Calculate the power 7^2. Add the values 49 and 28. Any expression multiplied by 1 is equal to itself. Find the derivative of 77+x^3-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 77+x^3-x. Substituting f(x+h) and f(x) on the limit, we get.
