graph ≥, ≤ correct answers solid line graph >, < correct answers DOTTED line every, each, per (writing equations) correct answers rate/ set y value equal to (multiply this value by the x variable) When writing an equation or working ANY inequality problem what does it help to do first? correct answers write out what's happening What should you double check for EVERY time correct answers writing problem down wrong (NEGATIVE SIGNS), uncarried negative signs, unflipped inequality signs, undotted lines, incorrect multiplication, fully simplified distance = correct answers rate x time When solving a system of equations can you add the equations together if one of the variables will cancel out? correct answers YES What should you always write out when doing your work? correct answers Fraction conversions, simplification steps, line graphs (interval notation) What standard does an equation/ graph have to meet to be considered a function? correct answers Each input can only have one output How do you translate a graph up or down? correct answers The value outside of the parentheses (DONT change sign) How do you translate a graph side to side? correct answers The value inside the parentheses (CHANGE SIGN) Translate -(x + 3)^3 - 2 from -x^3 correct answers left 3, down 2 When translating do you need to solve the equation? correct answers No, just look at the numbers inside (side to side change sign) and outside (up and down DONT change sign) the parentheses What is the domain? correct answers The x limits What is the range? correct answers The y limits U represents correct answers Numbers in EITHER set (Union) ⋂ represents correct answers Numbers in BOTH sets (Intersection)
