$derivdef\left(\frac{9}{4}-\frac{5}{4}\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of 9/4+-5/4 using the definition. Divide 9 by 4. Divide -5 by 4. Subtract the values \frac{9}{4} and -\frac{5}{4}. Find the derivative of 1 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 1. Substituting f(x+h) and f(x) on the limit, we get.
