Foundations of Functions

continuous "data whose input variable assumes real numbers, graphed as connected points"
dependent "can also be called output, y-axis, and range"
discrete "data whose input variable only assumes certain values, graphed in unconnected, distinct points, and has a domain that lists specific numbers. Ex. D={x|x=1, 2, 3, …}"
domain "the set of x-coordinates of the set of points on a graph or in a given set of ordered pairs, or the set of all inputs of a function"
function predictable relationship between two sets of numbers in which an input value from the first set has only one output value in the second set
function notation used to represent the dependency of a variable
independent "can also be called input, x-axis, and domain"
range "the set of y-coordinates of the set of points on a graph or in given set of ordered pairs, also known as the set of all outputs of a function"
scatterplot compares two sets of data to see relationships
