# Math Vocab Chapter 1

Question | Answer |
---|---|

coefficient | the numeral factor of a term |

continuois function | a function that can be graphed with a line or a smooth curve |

coordinate system | the grid formed by the intersection of 2 lines. the horizontal and vertical axis |

dependent variable | the variable in a relation with a value that depends on the value of the independent variable |

domain | the set of the first numbers of the ordered pairs in a relation |

end behavior | describes how the values of a function behave at each end of the graph |

function | a relation in which each element of the domain is paired with one element of the range |

identity | en equation that is true for every value of the variable |

independent variable | the variable in a function with a value that is subject to choice |

intercept | the graph of of a compound inequality containing AND; the solution is the set of elements common to both inequalities |

like terms | terms that contain the same variables, with corresponding variable having the same exponent |

line symetry | an imaginary line where you could fold an image and have both sides look exactly the same |

open sentence | a mathematical sentence with one or more variables |

order of operations | PEMDAS |

power | en expression of the form x (n), read x to the nth power |

range | the set of 2nd numbers of the ordered pairs in a relation; the difference between the greatest and least values |

relative maximimum | the value of a function at a certain point in its domain, which is greater or equal to values at all other points |

relative minimum | the point for all points in some region around |

replacement set | a set of numbers from which replacements for a variable may be chosen |

solution set | the set of elements from the placement that makes it an open sentence |

variable | symbols used to represent a number or value |

multiplication properties of 0 and -1 | 0- for any number, n times the number zero is zero -1- for any non-zero n times -1 is going to be a negative number unless the number being multiplied is also negative, then the producct will be positive |

Identity properties of addition and multiplication | addition- tells us that zero added to any number is the number itself. Zero is called the "additive identity multiplication- tells us that the number 1 multiplied times any number gives the number itself. |

commutative properties of addition and multiplication | add- a+b=b+a mul.- a*b=b*a |

associative properties of addition and multiplication | add- (a+b)+c= a+(b+c) mul.- (ab)c=a(bc) |

inverse properties of addition and multiplication | add- a+(-a)=(-a)+a=0 mul.- a*1/a=1/a*a=1 |

transitive property | 3+11=7+7 7+7=10+4 3+11=10+4 |

distributive property | allows us to get rid of parentheses and simplfy and expression |

f(x)=3x=2 | g(x)=x(t)-x |
