1 CLASS OPENER Pg. 11 – 13 #10, 55, 72

2 CLASS OPENER: You have 5 minutes to come up with the largest prime number you possible can.

3 A FUNCTION: A function f from set A to set B is a relation that assigns to each element x in the set A exactly one element y in the set B. The set A is the domain of the function f, and the set B contains the range of the function.

4 CHARACTERISTICS OF A FUNCTION 1.Each element of A much be matched with an element of B 2.Some elements of B may not be matched with any element of A 3.Two or more elements of A may be matched with the same element of B 4.An element of A cannot be matched with two different elements of B

5 EXAMPLE:

6

7 REVIEW OF FUNCTION NOTATION f(x) = range x = domain

8 EXAMPLE:

9

10 PIECEWISE FUNCTION A piecewise –defined function is a function that is defined by two or more equations over a specified domain. The absolute value function given by f(x) = x can be written as a piecewise – defined function.

11 EXAMPLE

12 EXAMPLE: Evaluate the function at each specified value of the independent variable and simplify a)f(-1)b) f(0)c) f(2)

13 IMPLIED DOMAIN

14 RADICAL FUNCTIONS Radical functions arise from the use of rational exponents. The most common radical function is the square root function.
