Order of Operations | P : Parentheses E : Exponents M : Multiplication D : Division A : Addition S : Subtraction |
Independent and Dependent Variables | A function is a correspondence or pairing between two variables such that each value of the first (independent) variable corresponds to exactly one value of the second (dependent) variable.. |
f(x) notation | X and Y variables can become to confusing so that is why f(x) notation is used. |
Finding Domain and Range from a Graph | Domain: the set of allowable values for the independent variable. Range: set of values of the dependent variable that result from all possible substitutions for the independent variable. |
Definition of a Function | A function is a relation in which no two different ordered pairs have the same first coordinate. |
Vertical Line Test for Functions | No vertical line intersects the graph of a function in more than one point. |
Distributive Property | For all real numbers a, b, and c, c( a + b ) = ca + cb |
Recursive Formula | ex: First Term = 40 New Term = previous term divided by 2 for all terms after the first |
Explicit Formula | Found by plugging in the nth term ex: Tn = 3n |
Clearing Fractions | To clear fractions in an equation multiply them all by a common denominator. |
