The typical rational function has the form p(x)/q(x) where p and q are polynomials. p(x) is called the numerator and q(x) is called the denominator. Example: In the rational function. which simplifies to simplifies to (x+2)/(x-3), but the x = 2 is NOT in the domain of g(x) whereas it IS in the domain of (x+2)/(x-3).
Power Functions. Basics. Definition. A power function is a function of the form, f (x) = axp, where a â  0 is a constant and p is a real number. Some examples of power functions include: Root functions, such as are examples of power functions.Graphically, power functions can resemble exponential or logarithmic functions for some values of x.he domain of a power function depends on the value of the power p. We will look at each case separately. 1. p is a non-negative integer. The domain is all real numbers (i.e. (â â,â)). 2. p is a negative integer. The domain is all real numbers not including zero (i.e. (ââ, 0) âª (0,â) or { x | x â  0}).
