Question | Answer |
---|---|
Quadrants | the four regions in which the coordinate plane is divided by the x-axis and the y-axis |
Coordinate Plane | the plane containnig the x- and y- axes |
X-Axis | the horizontal number line |
Y-Axis | the vertical number line |
Axes | two perpendicular number lines that are used to locate points on a coordinate plane |
Origin | the point of intersection of the two axes in the coordinate plane |
X-coordinate | the first number in an ordered pair |
Y-coordinate | the second number in an ordered pair |
Graph | to draw, or plot, the points named by certain numbers or ordered pairs on a number line or coordinate plane, respectively |
Relation | any pairing of a set of inputs with a set of outputs |
Domain | the set of x-coordinates in a function |
Range | the set of y-coordinates in a function |
Mapping | pairs one element in the domain with the element in the range |
Independent Variables | the input variable of a function |
Dependent Variables | the output variable of a function |
Linear Equation | an equation whose graph is a line |
Function | a pairing of inputs with outputs such that each input is paired with exactly one output |
Vertical Line Test | if any vertical line passes through no more than one point of the graph of a relation |
Functional Notation | a way to name a function using the symbol f(x) instead of y. The symbol f(x) is read as "the value of f at x" or as "f of x" |
Linear Inequality in Two Variables | an inequality that is the result of replacing the = sign in a linear equation with <,>, greater than or equal to, less than of equal to |
Graph of an inequality in two variables | the set of points in a coordinate plane that represents all solutions of the equation |
Half-Plane | in a coordinate plane, the region on either side of a boundary line |
Boundary | s line that separates the coordinate plane into half-planes |
