(12 cards)
Dependent Variable
Labeled on the y-axis; the quantity that is based on the input values of the independent variable, the output variable of a function
Curve
The graphical representation of a solution set for y=f(x); in the special case of a linear equation, the curve will be a line
Domain
The set of all inputs of a function, the set of x-values that are valid for the function
Function
A relation in which every element of the domain is paired with exactly one element of the range, that is for every value of x, there is exactly one value of y.
Function Notion
A way to move a function using f(x) instead of y
Independent variable
Labeled of the y-axis, the quantity that changes based on values chosen, the input variable of a function
Ordered pair
A pair of values (x,y) where the order is significant
Range
The set of all outputs of a function; the set of y-values that are valid for the function
Relation
A relationship between two sets of elements
Solution set
The value or values that make a sentence or statement true; the set of ordered pairs that represent all of the solutions to an equation or a system of equations
System
A set of more than one equation
Linear equation
An equation that can be written in the form ax+by=c, where a,b, and c are rational numbers; can be written as y=mx+b. M is the slope, b is the y-intercept, and the graph is a straight line. The solutions to the linear equations are the infinite set of points on the line
