Learn how to solve definition of derivative problems step by step online. Find the derivative of 12-17 using the definition. Subtract the values 12 and -17. Find the derivative of -5 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 -5. Substituting f(x+h) and f(x) on the limit, we get. Subtract the values 5 and -5. Zero divided by anything is equal to zero.
