$derivdef\left(-27x+16\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of (x-4)^2=x-28x+16 using the definition. Combining like terms x and -28x. Find the derivative of -27x+16 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 -27x+16. Substituting f(x+h) and f(x) on the limit, we get. Multiply the single term -27 by each term of the polynomial \left(x+h\right). Multiply the single term -1 by each term of the polynomial \left(-27x+16\right).
