Chapter 1 Flashcards
Variables
Symbols used to represent unspecified numbers or values
Vertical line test
See if a graph represents a function
Relation
A set of ordered pairs that can be represented as an equation, graph, table, or mapping how do you
Relative maximum
No other nearby points have a greater y-coordinate
Relative Minimum
No other nearby points have a lesser Y-coordinate
Replacement set
A set of Numbers from which replacements for a variable may be chosen
Simplest form
When it contains no like terms or parentheses
Solution
The replacement value
Term
Expressions maybe a number, a variable or product or quotient of a numbers and variables
Recipocal
2 numbers whose product is 1 (cannot be zero)
Power
The expression like (x the the second pwr)
Order of operations
The rule that lets you know which operation to perform first
Range
Set of the second numbers of the ordered pairs
Origin
At (0,0) The point where the axis intersex
Order pair
Is a set of numbers or coordinates written in the form (x,y)
Mapping
Illustrates how each element of the Domain is paired with an element in the range
Like terms
Terms that contain the same variables for corresponding variables having the same power
Dependent variable
The value is dependent on the value of the independent
Coefficient
Term is the numerical factor
Function
Is a relationship between input and output do you wish you
Base
Is X
Coordinate system
It’s formed by the intersection of two number lines (horizontal axis and the vertical axis)
Algebraic expression
Consist of sums and or products of numbers and Variables
Line symmetry
In the Y axis or some other vertical line if each half of the graph on either side of the line that is exactly
Intercept
Are the point to where the graph intersects axis
Independent variable
The value of the variable that determines the output
Exponent
Indicates the number of times that the base is used as a factor
Domain
The first set of numbers of the ordered pairs
End behavior
Describes the values of a function of the positive and negative extremes in its domain
Equation
Sentence that contains an equal sign
