Rate of change
Used to describe the measurement of the steepness of a straight line.
Parabola
Graph of a quadratic function
x-intercept
The x coordinate of a point where the graph crosses the x-axis.
Range
Set of all output (y) values you can plug into a function
Linear function
A function whose graph is a line. Same as Linear Equation.
Discrete Graph
The graph composed of isolated (only) points.
Linear Parent Function
y=x
y-intercept
The y coordinate of a point where the graph crosses the y-axis.
Growth factor
The "b" in y=ab^x. The rate at which something is growing or decaying.
Direct Variation
Linear function defined by an equation y=kx where k is not equal to 0.
Proportion
An equation that states that two ratios (fractions) are equal
Positive Slope
When a line increases
Point-Slope Form
A linear equation written as y - y1 = m (x - x1). The line passes through the point ( x1, y1) with slope m.
Continuous graph
A graph that is not broken
Ratio
The comparison of two quantities by division.
Exponential Decay
A situation modeled with a function of the form y=ab^x and 0 < b < 1.
Exponential Growth
A situation modeled with a function of the form y=ab^x and b > 1.
Quadratic Parent Function
y=x^2
Parent Function
The simplest function
Quadratic Equation
an equation with degree of 2
Asymptote
A line that the graph of a function gets closer to as x or y gets larger but never touches
Slope
Steepness of a line
Positive Correlation
The relationship between two sets of data in which both sets of data increase together.
Exponential function
A function that repeatedly multiplies an initial amount by the same positive number. y=ab^x
Slope-Intercept Form
Form of linear equation where m = slope and b = y-intercept.
Perimeter
Distance around a shape.
Function
A relationship where every input value (x) has one and ONLY one output value (y) X does not repeat!
Initial amount
The "a" in y=ab^x . What you begin with (also y-intercept).
Perpendicular Lines
Lines that intersect to form right angles (T)
Solutions
Also called roots, zeros or x-intercepts
Constant of variation
The nonzero constant "k" in the function y=kx
Line
Graph of a linear function
Domain
Set of all input (x) values you can plug into a function
Axis of symmetry
The line that divides a parabola into two matching halves
Negative Slope
When a line decreases
Standard Form
Ax+By=C where A, B, and C are real numbers and A & B are not both zero.
Negative Correlation
The relationship between two sets of data, in which one set of data decreases as the other set of data increases.
Linear equation
An equation whose graph forms a straight line.
Zero Slope
Horizontal Line
Linear Inequality
An inequality in two variables whose graph is a region of the coordinate plane that is bounded by a line. Each point in the shaded region is a solution.
No Correlation
There does not appear to be a relationship between two sets of data
Function notation
To write a rule by using the symbol f(x) in place of y
Quadratic Function
A function of the form y=ax^2+bx+c. Shape is a parabola (U-shaped curve) that opens up or down.
Binomial
A polynomial of two terms
Undefined Slope
Vertical Line
Vertex
The minimum or maximum values of quadratic functions. The axis of symmetry intersects the parabola at that point.
Parallel lines
Two lines in the same plane that never intersect (cross)
Relation
Any set of ordered pairs.
Area
Covers the shape.
Quadratic formula
if ax^2 + bx + c = 0 and a cannot equal 0, then
