Question | Answer |
algebra | a branch of mathematics dealing with symbols |
algebra expression | an expression that contains sums and/or products of variables and numbers |
coordinate plane | another name for coordinate system |
coordinate system | a coordinate system is formed by the intersection of two number lines that meet at right angles at their zero points, also called a coordinate plane |
counterexample | an example that shows conjecture is not true |
deductive reasoning | the process of using facts, properties, or rules to justify reasoning or reach valid conclusions |
defining a variable | choosing a variable and a quantity for the variable to represent in an equation |
domain | the domain of relation is the set of all x-coordinates from each pair |
equation | a mathematical sentence that contains an equal sign (=) |
evaluate | find the numerical value of an expression |
function | a function is a special relation in which each element of the domain is paired with exactly one element in the range |
function rule | the operation performed on the input of a function |
function table | a table organizing the input, rule, and output |
graph | a dot at the point that corresponds to an ordered pair on a coordinate plane |
numerical expression | a combination of numbers and operations such as addition, substraction, multiplication, and division |
