3.3 The logarithm as an inverse function
www.shsu.edu3.3.5 More on the logarithm as an inverse function We began this lecture by de ning g(x) = log b (x) as the inverse function of f(x) = bx. Since these functions are inverses, we know then that (f g)(x) = (g f)(x) = x: (15) Let us examine this in more detail. 123
Types of Functions Algebraic Functions
www-users.cse.umn.eduA function is called an algebraic function if it can be constructed using algebraic operations (such as addition, subtraction, multiplication, division and taking roots). Polynomials, power functions, and rational function are all algebraic functions. 1 Polynomials A function pis a polynomial if p(x) = a nxn + a n 1xn 1 + :::+ a 2x2 + a 1x+ a 0

(c) Find the number of years required for the frog population to reach 600. Solution (a): To find the function that models population growth, we need to find the . population n(t). To do this, we use the formula for population ...
Lecture 1 - UH
www.math.uh.eduDefinition 9. Let f be a one-to-one function. The inverse of f, denoted by f−1, is the unique function with domain equal to the range of f that satisfies f f−1(x) = x for all x in the range of f. Warning DON’T Confuse f−1 with the reciprocal of f, that is, with 1/f. The “−1”
