PART III. FUNCTIONS: LIMITS AND CONTINUITY
www.math.uh.eduPART III. FUNCTIONS: LIMITS AND CONTINUITY III.1. LIMITS OF FUNCTIONS This chapter is concerned with functions f: D → R where D is a nonempty subset of R. That is, we will be considering real-valued functions of a real variable. The set D is called the domain of f. Definition 1. Let f: D → R and let c be an accumulation point of D. A number L
Rational Functions - University of Utah
www.math.utah.eduRational Functions In this chapter, you’ll learn what a rational function is, and you’ll learn how to sketch the graph of a rational function. Rational functions A rational function is a fraction of polynomials. That is, if p(x)andq(x) are polynomials, then p(x) q(x) is a rational function. The numerator is p(x)andthedenominator is q(x ...
Chapter 2: Linear Functions - Mt. Hood Community College
www.mhcc.eduLinear Function A linear function is a function whose graph produces a line. Linear functions can always be written in the form f (x) =b +mx or f (x) =mx +b; they’re equivalent where b is the initial or starting value of the function (when input, x = 0), and m is the constant rate of change of the function Many people like to write linear functions in the form

ocw.mit.eduDelta Functions: Unit Impulse OCW 18.03SC t 1=2 2 q(t) =) t 1=2 1 Q(t) t 1=8 8 q(t) =) t 1=8 1 Q(t) Figure 1: two possible graphs of q(t) and Q(t), both with total input = 1. It is easy to see that each of the boxes on the left side of Figure 1 has total area equal to 1. Thus, the graphs for Q(t) rise linearly to 1 and then stay equal to 1 ...
Exponential Functions - University of Utah
www.math.utah.eduGraphs of exponential functions It’s really important that you know the general shape of the graph of an exponential function. There are two options: either the base is greater than 1, or the base is less than 1 (but still positive). Base greater than 1. If a is greater than 1, then the graph of f(x)=ax grows taller as it moves to the right.
RELATIONS & FUNCTIONS Worksheet
8theastviewmath.weebly.comThe only mapping that does not map a domain element to two or more range elements is Z. 16. A relation is a set of one or more ordered pairs. A function is a relation in which each element of the domain is paired with EXACTLY one element of the range. In the table below, there are two y-coordinates for the x-coordinate -10. Therefore, it is a ...
