Vocabulary • Relation – A set of ordered pairs. • Domain – A set of the x-coordinates. • Range – A set of the y-coordinates. • Quadrants – The 4 sections of a coordinate plane. • GCF – The biggest # or the most amount of variables we can divide each term by evenly. • Leading Coefficient - # in front of a variable eith the largest exponent.
Important Info • FOIL- First, outer, inner and last. • Foiling polynomials is the same thing as above. • Fundamental counting principle- if M can occur ‘m’ amount of ways and then N can occur a ‘n’ amount of ways then it can occur ways • Determine congruency. • Pythagorean theorem- in right angle triangles,
Identify Domain and Range, and whether it’s a function • (1,2) (5,6) (7,2) (3,-5) D: {x: 1,3,5,7} R: {y: -6,-5,2} yes 2) D: {x:-4,1,7 } R: {y:2,6,10,11 } no 1 -4 7 2 6 10 11
