Vocabulary
The set of all y-values.
What is range?
The domain of the relation {(5,-2),(-3,-2),(0,-2),(-2,-2)}
What is {-3,-2,0,5}?
A snow vendor collects data on the number of snow cones he sells per day and the daily temperatures. The dependent variable is this.
What is the number of snow cones?
This test is used to determine if a graph shows a function. If there is more than one intersection, the graph does not show a function.
What is the vertical line test?
Is the following relation a function? {(0,2),(-1,3),(3,2),(-4,5)}
Yes
A graph with connected points, usually showing a line or curve.
What is a continuous relation?
The range of the relation {(5,-2),(-3,-2),(0,-2),(-2,-2)}
What is {-2}?
A teacher wants to see if there is a relationship between her students' test scores and the amount of time they study. The independent variable is this.
What is the amount of time they study?
This is a graph of a function that has bends or curves.
What is a Nonlinear Function?
Is the following relation a function? {-2,2),(0,1),(-2,3),(3,-1),(0,3)}
No
A set of all the x-values.
What is domain?
The range of the function y=2x
What is the Set of All Real Numbers? Alternate answer: - infinity < y < infinity
Independent Variables are the ones found on this axis when graphed.
What is X-Axis?
This notation indicates that a relation is a function. It is another way to represent the output value while simultaneously displaying the input value.
What is function notation?
True or False? A function can have repeated y-values?
True
A graph with points not connected.
What is a discrete relation?
The range of the function y = x^2
What is all y-values greater than and equal to zero?
Alternate format: 0<x<infinity
In the following function, this is the independent variable y = 3x + 2
What is the X?
This is the only linear relation that is not a function.
What is a vertical line?
Functions cannot have repeated _______values.
What is X?
A graph, table or mapping diagram that shows no repeated x-values.
What is a function?
The range of the function y = 3x {Domain: 0,1,2,3,4)}
What is {0,3,6,9,12}?
In the following equation, this is the dependent variable P = 4s
What is P?
The result of evaluating function g(x)=3x-5 when x= -2
What is g(-2)=-11
What is the name of the method used to determine whether a graph is a function or not?
What is The Vertical Line Test?
