2 Functions Notes PDF | PDF We begin this discussion of functions with the basic de nitions needed to talk about functions. de nition 1. let x and y be sets. a function f from x to y is an object that, for each element x 2 x, assigns an element y 2 y . we use the notation f : x ! y to denote a function as described. The algebraic operations of addition, subtraction, multiplication and division etc. can be performed on two real valued functions suitably in the same manner as they are performed on two real numbers.

Functions | PDF Although high school math functions and cs functions are pretty different, they have two key aspects in common:. Find the domain and range of a function. determine whether a relation is a function. use the vertical line test to determine whether a graph is the graph of a function. express functions using proper functional notation. Definition of algebraic functions a function f is called an algebraic function if it can be constructed using algebraic operations such as addition, subtraction, multiplication or division or taking radical sign (starting with polynomial). Here are a few examples of functions. we will look at them in more detail during the lecture. very important are polynomials, trigonometric functions, the exponential and logarithmic function. you won't nd the h exponential in any textbook. we will have a bit of fun with them later.

Determine whether the graphs of the functions below are one to one functions. Note that messing with the input of a function changes the graph horizontally, while messing with the output changes the graph vertically. also, messing with the input always does the opposite of what you might expect. Function notation/evaluating a function: the notation y = f (x ) provides a way of denoting the value of y (the dependent variable) that corresponds to some input number x (the independent variable).
