Inverse of a Function
Inverse function: g(x) = x − 3 — 2 x −11357 y −2 −1012 The graph of an inverse function is a refl ection of the graph of the original function The line of refl ection is y = x To fi nd the inverse of a function algebraically, switch the roles of x and y, and then solve for y Finding the Inverse of a Linear Function Find the inverse
A Guide to Functions and Inverses
7 Inverse of a Linear Function The method of getting the equation of an inverse of a linear function is discussed It is also given that the gradient would remain the same but the y-intercept would most
44 Solving Congruences using Inverses
inverse of a modulo m is congruent to a modulo m ) Proof By B ezout’s Theorem, since gcdpa;mq 1, there exist integers s and t such that 1 sa tm: Therefore sa tm 1 pmod mq: Because tm 0 pmod mq, it follows that sa 1 pmod mq: Therefore s is an inverse of a modulo m To show that the inverse of a is unique, suppose that there is another inverse
Math 133 Inverse Functions What is a function? Like other
Math 133 Inverse Functions Stewart x6 1 What is a function? Like other mathematical concepts, the idea of a function has four levels of meaning: physical (word problems), geometric (graphs), numerical (spread-sheets), and algebraic (formulas) We illustrate these with the following example Physical
