Chapter 3: Transformations of Graphs and Data Lesson 1: Changing Windows Mrs. Parziale

Vocabulary Transformation: is a one-to-one correspondence between sets of points. Two types of transformations: Translations Scale Changes Asymptote: a line that the graph of a function approaches and gets very close to, but never touches. Parent function: the general form of a function, from which other related functions are derived.

Set Notation Reminder Use the following notation when describing domains and ranges of various functions. is read "the set of all x, such that x is an element of the real numbers and x is greater than 0." is read "the set of all y, such that y is an element of the real numbers and y is greater than -5 and less than +5."

Example 1: Using your calculator, graph y = 2x on the following windows and sketch each below:
