1) Take notes from the podcast
2) Make sure you have all the definitions from the bottom of the tutorial written down.
CONTINUOUS: A set with no breaks in domain or range
DECREASING: A function that goes down as you move across the graph from left to right
DEPENDENT: A variable that changes because of the independent variable; y-variable; output
DISCRETE: A set with breaks in the domain or range
DOMAIN: The set of all inputs or x-values for a function
FINITE: A set that ends. Shown on a graph with using points at the ends.
FUNCTION: A relationship where every input has one and only one output
INCREASING: A function that goes up as you move across the graph from left to right
INDEPENDENT: A variable that is chosen by you; x-variable; input
INFINITE: A set that never ends; lasts forever. Shown on a graph using arrows at the ends.
INPUT: A term or number that is plugged into a relationship; the x-variable in an ordered pair
LINEAR: A function in the shape of a line
NON LINEAR: A function not in the shape of a line; curve
RANGE: The set of all outputs or y-values for a function.
RELATIONSHIP: A comparison of terms, variables, and/or numbers (typically an equation or inequality)
OUTPUT: A term or number that is the answer or solution to a relationship; the y-variable in an ordered pair
VERTICAL LINE TEST: A test that uses vertical lines to check if a graph is a function. Each vertical line can intersect a graph only once for a graph to be a function.
