$derivdef\left(-1+x^2-2x-3x^2-4x\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of x^2-2x+4-3x^2-4x+-5 using the definition. Subtract the values 4 and -5. Combining like terms x^2 and -3x^2. Combining like terms -2x and -4x. Find the derivative of -1-2x^2-6x 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 -1-2x^2-6x. Substituting f(x+h) and f(x) on the limit, we get.
