Derivative power rule proof
Webcontributed In order to differentiate the exponential function f (x) = a^x, f (x) = ax, we cannot use power rule as we require the exponent to be a fixed number and the base to be a variable. Instead, we're going to have to start with the definition of the derivative: WebSep 7, 2024 · The derivative of a power function is a function in which the power on \(x\) becomes the coefficient of the term and the power on \(x\) in the derivative decreases …

WebProof of the derivative rule for exponential functions Recall that $\dfrac{d}{dx} f(x) = \lim_{h\rightarrow 0}\dfrac{f(x + h) – f(x)}{h}$, so we can use this to confirm the derivative that we’ve just learned for $y = a^x$. Use the product rule for exponents,$a^{m} \cdot a^n = a^{m+n}$, to factor $a^x$ from the numerator.
