The limit definition of the derivative leads to patterns among certain families of functions that enable us to compute derivative formulas without resorting directly to the limit definition. The derivative of any exponential function is another exponential function: for example, if \(g(z) = 7 \cdot 2^z\text{,}\) then \(g'(z) = 7 \cdot 2^z \ln(2)\text{,}\) which is also exponential. }\) Apply this rule to \((x+h)^4\) within the limit definition. cos Whether you're an experienced meteorologist honing existing The Exponential Integrate-and-Fire model, 3.
