You "input" money and your "output" is candy or chips! We're going to go back to that visual as we begin evaluating functions. We are going to "input" a number and our "output" is the answer. Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions.

Functions: a relation where each element in the domain is paired with exactly one element in the range. All functions are relations, but not all relations are functions; Rule: expresses an output value in terms of an input value; Determining if a Relation is a Function: when drawn on a coordinate plane: Discrete Math Cheat Sheet/Study Sheet/Study Guide in PDF: Cheat sheet/study sheet for a discrete math class that covers sequences, recursive formulas, summation, logic, sets, power sets, functions, combinatorics, arrays and matrices. From a night class at Fordham University, NYC, Fall, 2008 14. RELATIONS AND FUNCTIONS RELATIONS In mathematics, we study relations between two sets of numbers, where members of one set are related to the other set by a rule. Relations are also described as mappings. When we map a set of numbers onto another set of numbers, we often express the rule for

Then state the number of real zeros. As x → -∞, f(x) → -∞ and as x → +∞, f(x) → +∞, so it is an odd-degree polynomial function. Study Guide SStudy Guide and Reviewtudy Guide and Review Key Concepts Functions (Lesson 1-1) • Common subsets of the real numbers are integers, rational numbers, irrational numbers, whole numbers, and natural numbers. • A function f is a relation that assigns each element in the domain exactly one element in the range. The function f has domain [ ±8, ) and range [0, ). Fí1(x) = x2 í 8 From the graph y = x2 ± 8 below, you can see that the inverse relation has domain ( ± , ) and range [8, ). By restricting the domain of the inverse relation to [0, ), the domain and range of f are equal to the range and domain of f ±1, respectively.

Chapter 2.1 Relations and Functions Objectives: • Analyze and graph relations. • Find functional values. Algebra II A function is a relation in which each element of the domain is paired with exactly one element of the range. An easier definition is, for each x-value, there is only one y-value. Relation is shown below. Functions and relations A function is a relation for which each value from the domain is associated with exactly one value from the codomain. Functions can be either one to one or many to one. Consists of crates. Many eggs can be packed in the Relations can be one to one, many to one, one to many or many to many.

Example 1: Write each equation in standard form. Identify A, B, and C. A. Y = 8x – 5 y = 8x – 5 Original equation

Iv. A function is a relation that assigns exactly one value in the range to each value in the domain v. Vertical Line Test: If a vertical line passes through more than one point of the graph, the relation is not a function vi. A function rule is an equation that describes a function. You can think of a function rule as an input-output machine vii. Marketing is the bridge between the product and the customer. A marketer uses the four P's -- product, price, place, and promotion -- to communicate with the consumer. Promotion is a combination of all forms of communication to the customer, including advertising and public relations.
