(50 cards)
algebraic expression
an expression that contains at least one variable
point slope form
y-y₁=m(x-x₁)
experimental probability
Probability that is based on repeated trials of an experiment
Transformation
change of a parent function
function notation
Fx
scatter plot
A graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables. The amount of scatter suggests the strength of the correlation
stretch
spread out
linear inequality
An inequality in two variables whose graph is a region of the coordinate plane that is bounded by a line.
constant of variation
the number k in equations of the form y=kx
range
all y values
parameter
(n.) a determining or characteristic element; a factor that shapes the total outcome; a limit, boundary
absolute value of a real number
The distance from zero on a number line
term
Each number in a sequence
translation
A shift of a graph horizontally, vertically, or both, which results in a graph of the same shape and size, but in a different position.
parent function
the most basic function in a family of functions
solution of an equation
a value or values that make an equation true
shrink
Reduces y values by a factor between 1-0
absolute value
The distance a number is from zero on a number line and distance is non negative
linear equation
an equation whose graph is a straight line
coefficient
A number multiplied by a variable in an algebraic expression.
extraneous solution
an apparent solution that must be rejected because it does not satisfy the original equation
additive inverse
The opposite of a number
variable expression
An expression that consists of numbers, variables, and operations
dependent variable
a variable (often denoted by y ) whose value depends on that of another.
reciprocal
1 divided by the number
Multiplicative Inverse
The reciprocal of a number
independent variable
a variable (often denoted by x ) whose variation does not depend on that of another.
absolute value of a function
a function written in the form y = /x/, and the graph is always in the shape of a v
reflection
A transformation that "flips" a figure over a mirror or reflection line.
simulation
an imitation of a possible situation, a model
mapping diagram
Links the elements of the domain with corresponding elements of the range
domain
The set of input values of a function. The x value
relation
any set of ordered pairs
trend line
a line on a scatter plot drawn near the points. it shows a correlation
evaluate
when you substitute numbers for a variablr
function
1. A relationship from one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range. 2. The action or actions that an item is designed to perform.
linear function
A function whose graph is a straight line.
compound inequality
Two or more inequalities that are connected by the words and or or.
tolerance
equals one half the difference between max and min values
Sample Space (Probability)
list of all possible outcomes
vertical line test
a visual way to determine if a curve is a graph of a function or not.
theoritical probability
likelihood that a particular event will occur
slope-intercept form
y=mx+b
standard form
Ax + By = C
variable
A symbol used to represent a quantity that can change
opposite
Having a different sign but the same numeral.
vertex
The common endpoint of an angle
x-intercept
where the graph crosses the x-axis
slope
Rise over run
direct variation
The relationship between two variable quantities that have a constant ratio.
