Learn how to solve definition of derivative problems step by step online. Find the derivative of 22xx using the definition. When multiplying two powers that have the same base (x), you can add the exponents. Find the derivative of 22x^2 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 22x^2. Substituting f(x+h) and f(x) on the limit, we get. Expand \left(x+h\right)^2. Multiply the single term 22 by each term of the polynomial \left(x^2+2xh+h^2\right).
