x = $$\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

A mathematical sentence with an =.

Simplest radical form

No square root in the denominator—bottom of the fraction—and any perfect square factors factored out of the radical symbol

Linear regression equation

Uses stat, L1 and L2, LinReg, BUT must write in y = mx + b by plugging in the a and b found by the calculator

Give an answer with 2 decimal places. Round based on the 3rd decimal place but don’t write it.

Correlation coefficient

The r on the screen when you use LinReg. Turn on the r first, using 2nd, 0 for catalogue, scroll down to DiagnosticON, hit enter twice to turn it on.

Break a polynomial into greatest common factor and binomial factors like (x- zero).

Method of completing the square

Factor with a square box, add or subtract constant so that the left hand side of the equation is a perfect square trinomial, rewrite the trinomial as a binomial squared, square root both sides, add or subtract to isolate x.

An answer with a square root left in, if the calculator gives you an irrational decimal.

Two-way frequency table

Show data with percents or number of times where all columns and rows have sums on the bottom or right.

Questions asked of a sample of people to gather data.

The information stated in the problem.

Give a value or number, usually plugging a number into an expression.

Solution to the equation

Whatever x correctly equals, can be stated in { }

The set of all possible x values

The set of all possible y values

Change in distance over change in time

A pattern of numbers where the domain is the position in the list and the range are the numbers themselves

When data is shown by dots over a number line

Add all the numbers and divide by the number of numbers

Middle number of an ordered list

Data number that occurs most often

Math functions that represent situations

Average rate of change

Slope, calculated as change in y over change in x

Q3-Q1, on a box and whisker graph, the number at the right end of the box minus the number at the left end of the box

Parabola, smile or frown, an equation of degree 2

Lowest point on a graph—vertex of a smile

Highest point on a graph—vertex of a frown

Also called roots or solutions, they are at x-intercepts

Common ratio of a sequence

The multiplier in a sequence (pattern)

System of inequalities

2 or more inequalities—math statements with greater than or less than instead of =

A decimal that does not repeat or stop but goes across your calculator screen with no pattern
