Absolute Value - The distance a number is from zero, always positive. |-3| = 3 and |3| = 3
Binomial - an expression with two terms
Coefficient - A number in front of a variable, multiplying by the variable.
Constant - A value that stands alone and never changes.
Cube Root - A radical with an index of 3.
Degree - A number that represents the highest exponent in that polynomial
Dependent - the variable that depends on the other variable. The y-axis. The thing that is not in your control.
Distributive Property - Describes how many identical groups there are. Multiply the term outside the parenthesis by each term in the parenthesis.
Domain - The x values in a function. Describes the length of the graph.
Exponent - A number written in the upper right hand corner representing how many times a value is multiplied by itself.
Expression - A math sentence including terms and operations but no equal sign.
FOIL - the process of multiplying two polynomials by multiplying the first, outside, inside, then last terms.
Function - A relationship where all x values get exactly one different y value. Must pass the vertical line test.
Horizontal - A line created when the points have the same y value. Written as y equals a number.
Independent - The variable that can stand alone or never changes (ex. time). It is the input of the equation. The x-axis values.
Inequality - states a number must be greater, less, or equal to a variable, solved like an equation, has many solutions
Intercepts - Where a line crosses the x or y axis, zeroes
Like Terms - Terms that have the same variables and powers, or constants.
Monomial - A single term which contains a variable
Operation - A math symbol that dictates to multiply, divide, add, or subtract.
Order of operations - The order in which every math problem is simplified.
Parallel - two lines on the same plane that will never intersect. Linear equations with the same slope and different y-intercepts
Perfect Square - a number that can be square rooted and produce an integer other than 0
Perpendicular - two lines on the same plane that intersect to create 4 right angles. Linear equations with opposite reciprocal slopes.
Point-slope - the way a line is written using a point and slope. y - y, = m (x - x,)
Polynomial - an expression containing 4 or more terms
Power Properties - how exponents are written and the value they represent
Quadratic - an expression with a degree of 2
Radical - another word for a root (square root, cube root...)
Range - the height of a graph, determined by the y values in the graph listed least to greatest or in interval notation
Real numbers - positives, negatives, whole numbers, fractions, decimals and radicals
Relation - A set of points, or input/outputs that can be graphed on a coordinate plane
Roots - where a function equals zero, mainly used in quadratics, also used to describe radicals
Scatterplot - a collection of data represented on coordinate plane using points
Simplify - having the same value using simpler (smaller) terms or numbers, combining like terms, dividing a fraction by one (using gcf).
Slope - the steepness and direction of a line. The variable m represents slope. Found by finding the change in y and dividing it by the change in x.
Slope-intercept - a way to write a linear equation (y = mx + b), contains both slope and y-intercept within the equation.
Solutions - Answers to systems of equations, written as points
Square root - a radical symbol dictating to find a number that was multiplied by itself to yield the value under the radical.
Standard form linear - an equation written in the form Ax + By = C where the x coefficient is non-negative, A, B and C are whole numbers, and no coefficients are 1.
Systems of equations - two or more equations (or inequalities) that will intersect at one point, the solution. Methods for solving: substitution, graphing, elimination
Term - Part of an expression; a coefficient pair, constant or variable
Trinomial - an expression containing 3 terms
Variable - A placeholder, usually a letter, that represents an unknown value.
Vertex - the turning point for a parabola
Vertical - a straight line parallel to the y-axis; written as x equals a value
Zeros - where a function crosses the x-axis
