 Names/meanings for: X Domain, Independent Variable, Time, Input Women have X chromosomes Names/meanings for: Y Range, Dependent Variable, Output Men have Y chromosomes Functions Can't have repeating X values Vertical line test (vertical line can only cross function once) Corrdinate values (X,Y) X comes before Y in the alphabet Axis labels X axis-horizontal axis Y axis-vertical axis X goes left to right Y goes up and down Slope/Rate of Change Change in Y's/change in X's Vertical change/Horizontal change (Y2-Y1)/(X2-X1) Leans to right/goes up-Positive; Leans to left/goes down-Negative; Straight up and down-No slope; Goes left to right-zero slope Linear Function y=mx+b; m is slope; b is y-intercept; graph is a straight line Line is first four letters of Linear Quadratic Function y=ax²+bx+c; +a=U shaped; -a=n shaped; a=big whole #-U gets more narrow; a=small fraction #-U gets wider U in qUadratic describes the shape of the graph Absolute Value y=|x|; any # for x - or + comes out positive; ex: y=|-4| =4 V in Value describes the shape of the graph Y Intercept Where the function crosses the y-axis. (0,#); x is always 0 called "b" in slope intercept form X Intercept Where the function crosses the x-axis. (#,0); y is always 0 Also known as roots or solutions ≥ Greater than or Equal to: denoted by a solid point & arrow going right on # line --or-- denoted by a solid line & shading above the line on a graph left side is bigger than or = to the right side Percents Part/Whole= %/100 move decimal 2 places to the left > Greater than: denoted by an open circle & arrow going right on # line --or-- denoted by dotted line and shading above line on graph left side has to be bigger than the right side < Less than: denoted by an open circle & arrow goin left on # line --or-- denoted by dotted line and shading below line on graph Left side has to be smaller than the right side ≤ Less than or Equal to: denoted by solid point & arrow going left on # line --or-- denoted by solid line and shading below line on graph Left side has to be smaller than or = to the right X^a * X^b X^a+b When you x your letters you + your exponents. (X^a)/(X^b) X^(a-b) When you / your letters you - your exponents. (X^a)^b X^(a*b) When you ^ a power to another power you x your exponents. a less than b b-a Less than=taken away from; you have to have b before you can take a away from it Associative property (a+b)+c=a+(b+c) (a*b)*c=a*(b*c) You can associate with people around you without moving. Commutative property a+b=b+a a*b=b*a You commute to and from school. Distributive property a(b+c)=a*b+a*c You have to distribute the a to everything in the parenthesis. "Share the Love" When you are given a table with info. & you have functions as answer choices (Also works when given any two points or coordinates.) 1. Put table in STAT function & calculate either linear regression or quadratic regression 2. Put each function in y= and push 2nd Table and compare. (Equations must be in y=format) STAT-EDIT-put x's under L1 & y's under L2-STAT-→-CALC-4 Linear Regress. or 5 Quadratic Regress. a²+b²=c² Pythagorean Thereom; Can be used anytime you have a right △ and are missing only one side; (Area of □ with side length a + Area of □ with side length b=Area of □ with side length c) c=hypotenuse (always the longest side); a+b>c; a
