By the end of this tutorial students will be able to identify if a table shows a function using the definition of a function.
Students will be able to check their assumption by plotting the points/graphing the equation and using the vertical line test.
1) Take notes from the podcast
FUNCTION: A relationship where every input has one and only one output
INPUT: A term or number that is plugged into a relationship; the x-variable in an ordered pair
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.
