Term | Definition |
---|---|
Function | A relationship in which for each input there is one output |
Domain | The set of all input (x) values for a function |
Range | The set of all output (y) values for a function |
Slope | A ratio that shows how steep or flat a line is |
Linear Equation | A function whose graph is a straight line because of a constant rate of change |
y-intercept | The point where the graph intersects the y-axis |
x-intercept | The point where a graph intersects the x-axis |
slope-intercept form | One of the ways to write a linear equation |
proportional | Each output (y) is determined by multiplying the input (x) by a constant number. The graph is a line that goes through the origin |
sum | The result of adding two or more numbers |
difference | The result of subtracting two numbers |
product | The result of multiplying two or more numbers |
quotient | The result of dividing two numbers |
order of operations | The specific order to do operations when simplifying an expression: 1. Grouping symbols, 2. Exponents, 3. Multiplication or Division (L to R) 4. Add or Subtract (L to R) |
variable | A symbol (usually a letter in the alphabet) used to represent one or more numbers |
expression | A collection of variables and numbers connected by addition, subtraction. multiplication, and/or division |
equation | A mathematical sentence in which two expressions are equal to each other |
coefficient | A number that multiplies a variable |
polynomial | An expression written as the sum or difference of terms in one variable with whole number exponents |
binomial | A polynomial that is made up of two terms |
monomial | A polynomial that has one single term |
trinomial | A polynomial that is made up of three terms |
distributive property | A way to simplify expressions |
perimeter | Total distance around a geometric shape |
area | Number of square units needed to cover geometrical shape |
complementary angles | Two angles whose sum is 90* |
supplementary angles | Two angles whose sum is 180* |
symmetry | When a shape looks exactly the same after a flip, turn, or slide |
Rigid transformation | Moving a geometrical shape without changing size or shape |
translation | Slides a shape to a new location |
rotation | Turn all points in a shape the same number of degrees around a given point |
reflection | Flips a shape over a line to create a mirror image of the shape |
least-squares regression line | Line of best fit for data on a scatterplot |
residual | Difference between a predicted value and the actual value |
correlation coefficient | A measure of how scattered data is around the line of best fit |
lurking variable | A hidden factor that explains the true cause of an association |
scatterplot | A graph displaying two-variable data the x- and y-axis |
independent variable | Changes in this quantity are not a result of changes in the other variable |
dependent variable | Changes in this quantity are a result of changes in the other variable |
outlier | A data value that is not within the normal pattern of the data |
arithmetic sequence | A number pattern that increases or decreases by a constant value ie: 3,6,9,12... |
geometric sequence | A number pattern that multiplies by te same value each time ie: 4,8,16,32... |
common ratio | The constant multiplier for a given sequence |
common difference | The constant increase or decrease in a given sequence |
recursive equation | An equation used to generate the next term in a sequence ie: t(n+1)=t(n)+m |
explicit equation | An equation used to determine any term in a sequence based on the term number ie: t(n)=mn+t(0) |
