1. The question asks about the "map of e forming rules," which seems to involve understanding the exponential function with base $e$, the natural exponential function. 2. The exponential function is defined as $$f(x) = e^x,$$ where $e \approx 2.71828$ is the base of the natural logarithm. 3. This function has several important properties: - $e^{x+y} = e^x \cdot e^y$ (Exponent addition rule). - $e^0 = 1$. - The derivative of $e^x$ with respect to $x$ is $e^x$. 4. If your question refers to the rules for mapping or transforming expressions involving $e$, such as differentiation, integration, or simplification, these hinge on the above exponential properties. 5. Please clarify if you want specific rules for exponential equations, transformations, or related graphs, so I may assist more precisely.
