âThat meant representation for all.â. Since then, the best of North Carolinaâs legislative leaders, though not all, have presided over its chambers with an eye toward good government. But last weekâs session was a reversion to the strong-arm rule that Republicans decried in the 1980s.
An identity function is a function that always returns the same value as its argument. In other words, the identity function is the function f(x) = x. x.
The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent. A simple example is the function $$f(x)=2^x.$$. As illustrated in the above graph of $f$, the exponential function increases rapidly. Exponential functions are solutions to the simplest types of dynamical systems.
