a form of logical thinking that uses generalizations to draw specific conclusions based on a series of logical steps, deductive reasoning may use rules, laws, and theories to support or justify a conjecture

a value or variable that depends upon the independent value

a value or variable that depends upon the independent value

a pattern made of separate and distinct values or objects

values that change in increments (not continuously)

the expression b2 – 4ac under the radical in the quadratic formula; the expression can be used to determine the number of real roots the quadratic equation has

states that the product of a number and a sum equals the sum of the individual products of the number and the addends: for all real numbers a, b, and c, a(b + c) = ab + ac

allows us to divide both sides of an equation by the same amount: For all real numbers a, b, and c, if a = b and c is not 0, then

the set of all possible inputs of a function which allow the function to work
