Discrete Graph
|
The graph is only distinct points. The values between the whole numbers are not included because they have no meaning for the situation.
|
|
Continuous Graph
|
The graph is connected points or curves. The values between the whole numbers are included because the have meaning for the situation.
|
|
Relation
|
A set of ordered pairs...used to represent a relationship
|
|
Domain
|
the set of the first coordinates (or x-values) of the ordered pairs of a relation
|
|
Range
|
the set of the second coordinates (or y-values) of the ordered pairs of a relation
|
|
Function
|
special type of relation that pairs each domain value (x) with exactly one range value (y)...no x repeats!
|
|
Independent Variable
|
the input of a function
x-values domain |
|
Dependent Variable
|
the output of a function
y-values range |
|
Function Rule
|
an algebraic expression that defines a function
|
|
Function Notation
|
if y depends on x, then y can be replaced with f(x),"",, read "f of x"
|
|
Graphing Functions Using Domain of All Real Numbers
|
1. Choose several values for x
2. Substitute the chosen values for x to generate ordered pairs (x,y) 3. Plot the points and connect with smooth line or curve |
|
Scatter Plot
|
a graph with points plotted to show a possible relationship, or correlation, between two sets of data
|
|
Correlation
|
describes a relationship between two sets of data...may be shown by a graph...helps you analyze trends and make predictions
|
|
Positive Correlation
|
Both sets of data values increase...as x increases, y also increases
|
|
Negative Correlation
|
In a set of data, as the x-values increase, the y-values decrease
|
|
No Correlation
|
In a set of data, there is no relationship between the x-values and the y-values
|
|
Trend Line
|
a line graphed on a scatter plot to help show a relationship in the data...can be used to make predictions based on the data
|
|
Sequence
|
a list of numbers that may form a pattern...each number in a sequence is called a term
|
|
Arithmetic Sequence
|
a sequence in which the terms of a sequence differ by the same nonzero number, called the common difference
|
