(50 cards)
Parallel
Two lines that never intersect. They have the same slope.
Rate of Change
Another way to say slope
Exponent
When a number is raised to a power (multiplied by itself).
Distributive Property
Allows you to multiply an expression by multiply each term individually and then adding the products.
Inequality
The relation between two expressions that are not equal.
Roots
The solutions, zeros or x-intercepts of a quadratic function.
Polynomial
An expression that contains several terms including coefficients, variables, and exponents.
Range
The set of all possible output values for a function.
Positive Correlation
A relationship between two variables such that as one increases, so does the other.
Origin
Where the x and y-axes meet. (0,0)
Continuous Data
Data that consists of all numbers on an interval.
Reciprocal
One divided by the number. Flip the fraction.
Coefficient
The number in front of the variable.
Domain
The set of all possible input values of a function. The x-values.
Quadratic Parent Function
The most basic quadratic function. y = x^2
Quadratic Equation
An equation whose highest power is a 2.
Dependent Variable
The variable that represents the output of a function. Usually the y-variable.
No Solution (Quadratics)
When there is no value that satisfies a given equation.
Independent Variable
The variable that represents the input of a function. Usually the x-variable.
Intercept
The place where a graph crosses the x or y-axis.
Non-linear Function
Any function that does not make a straight line.
Exponential Function
Area
The total amount of space a two-dimensional shape takes up.
Exponential Growth
When a value increases by a constant multiple.
Slope
The rate of change between any two points on a line.
Point-Slope Form
Solve
To isolate a variable and/or identify a value that satisfies an equation.
One Solution (Quadratics)
When there is exactly one value that satisfies an equation.
Constant of Variation
The number that relates two variables that are directly or inversely proportional.
Perimeter
The sum of the lengths of all the sides of a polygon.
Simplify
To use the rules of arithmetic and algebra to rewrite an expression.
Discrete Data
A data set that consists of only certain numbers in an interval.
Function Notation
Solution
A value that satisfies an equation. For a quadratic it is also called a root, zero, x-intercept.
Slope intercept form
Perpendicular
Two lines that intersect to form 90 degree angles. They have opposite reciprocal slopes.
Quadratic Function
A non-linear function whose highest power is a 2. makes a parabola when graphed.
Intersection
The point where two lines cross.
Parabola
The U shaped graph of a quadratic function.
Exponential Decay
When a value decreases by a constant multiple.
System of Equations
Two or more lines. The solution to a system is where these two lines intersect.
Quotient
When two numbers are divided.
Factor
When you break an expression down into smaller expressions multiplied together.
Direct Variation
An equation of the form y = kx. Passes through the origin and is a straight line.
Product
When two numbers are multiplied together.
Binomial
An expression containing two terms.
Term
One piece of an expression. No addition or subtraction.
Function
An expression or equation for which every input has exactly one output. No repeating x's. Passes the vertical line test.
Standard Form
Ax + By = C y = ax^2 + bx + c
Axis of Symmetry
The vertical line that divides a parabola into two symmetric parts.
