| algebraic expression | an expression consisting of one or more numbers and variables along with one or more arithmetic operations. |
| coefficient | the numerical factor of a term |
| continuous function | a function that can be graphed with a line or a smooth curve |
| coordinate system | the grid formed by the intersection of two number lines, the horizontal axis and the vertical axis |
| dependent variable | the variable in a relation with a value that depends on the value of the independent variable |
| discrete function | a function of points that are not connected |
| domain | the set of the first numbers of the ordered pairs in a relation |
| factor | in an algebraic expression, the quantities being multiplied are called factors |
| function | a relation in which each element of the domian is paired with exactly one element of the range |
| independent variable | the variable in a function with a value that is subject to choice |
| inequality | an open sentence that contains the symbol [math] < , \le , > , \ge [math] |
| integers | the set {...,-2,-1,0,1,2,...} |
| irrational numbers | numbers that cannot be expressed as terminating or repeating decimals |
| like terms | terms that contain the same variables, with corresponding variables having the same exponent |
| multiplicative inverse | two number with a product of 1 |
| range | the set of second numbers of the order |
| rational number | the set of numbers expressed in the form of a fraction a/b, where a and b are integers and $$b \ne 0$$ |
| real numbers | the set of rational numbers and the set of irrational numbers together |
| reciprocal | the multiplicative inverse of a number |
| variable | symbols used to represent unspecified numbers or values |

| formula | an equation that states a rule for the relationship between certain quantities |
| mixture problems | problems in which two or more parts are combined into a whole |
| number theory | the study of numbers |
| percent of change | when an increase or decrease is expressed as a percent |
| percent of decrease | the ratio of amount of decrease to the previous amount, expressed as a percent |
| percent of increase | the ratio of amount of increase to the previous amount, expressed as a percent |
| proportion | an equation of the form a/b=c/d stating that two ratios are equivalent |
| rate | the ratio of two measurements having different units of measure |
| ratio | a comparison of two numbers by division |
| scale | a ratio or rate used when making a model of something that is too large or too small to be conveniently shown at actual size |
| weighted average | the sum of the product of the number of units and the value per unit divided by the sum of the number of units, represented by M |
| arithmetic sequence | a numerical pattern that increases or decreases at a constant rate or value. The difference between successive terms of the sequence is constant. |
| function | a relation in which each element of the domain is paired with exactly one element of the range |
| function notation | A way to name a function that is defined by an equation. In function notation, the equation y=3x-8 is written as f(x)=3x-8 |
| inverse | the inverse of any relation is obtained by switching the coordinates in each ordered pair |
| linear equation | an equation in the form Ax+By=C, with the graph that is a straight line |
| sequence | a set of numbers in a specific order |
| term | a number, a variable, or a product or quotient of numbers and variables |
| x-intercept | where a function crosses the x-axis |
