25 terms
Terms | Definitions |
|---|---|
 monomial | an expression with only one term |
| domain | The set of x-coordinates of the set of points on a graph; the set of x-coordinates of a given set of ordered pairs. The value that is the input in a function or relation. |
| range | The y-coordinates of the set of points on a graph. Also, the y-coordinates of a given set of ordered pairs. The range is the output in a function or a relation. |
| linear equation | an equation whose solutions form a straight line on a coordinate plane. |
| vertex | the point of intersection of the two rays that form the sides of the angle |
| intercept | the point at which a line intersects a coordinate axis |
| axis of symmetry | A line that divides a figure in half so that each half is the mirror image of the other |
| integer | The set of whole numbers and their opposites |
| absolute value | The distance a number is from zero on a number line |
| intersecting lines | Lines that cross at exactly one point |
| polynomial | a mathematical expression that is the sum of a number of terms |
| cordinate plane | - formed by two real number lines that intersect at a right angle |
| ordered pair | A pair of numbers, (x, y), that indicate the position of a point on a Cartesian plane. |
| square number | The product of a number multiplied by itself. |
| function | a mathematical relation such that each element of one set is associated with at least one element of another set |
| combine like terms | to add or subtract like terms. Ex: 3x and- 5x combine to become -2x. |
| constant difference | the difference that is always the same from one term to the next number |
| algebraic expression | A mathematical phrase involving at least one variable and sometimes numbers and operation symbols. |
| exponent | a mathematical notation indicating the number of times a quantity is multiplied by itself |
| term | any distinct quantity contained in a polynomial |
| maximum | the point on a curve where the tangent changes from positive on the left to negative on the right |
| minimum | the point on a curve where the tangent changes from negative on the left to positive on the right |
| slope | the steepness of a line on a graph, equal to its vertical change divided by its horizontal change |
| variable | a symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity |
| negative exponent | an exponent less than zero which causes the base and its exponent to move positions in a fraction |
