Terms in this set (38)
Integers
A whole number that can be positive, negative, or zero, It can be positive and negitive.
Whole Numbers
Positive numbers, including zero, without any decimal or fractional parts. 0,1,2,3,4...
Irrational Numbers
A number that cannot be written as a quotient of integers Icluding π
Rational Numbers
A number that can be written as a quotient of integers Ex. -2/5
Natural Numbers
Numbers that occur commonly and obviously in nature. Counting numbers
Laws Of Exponents
-In order to add/subtract you must have like terms
-When multiplying with exponents add the exponents
-Apply the power to each factor and simplify(distribution)
-When raising an exponents to a power multiply the exponent
-When dividing with exponents subtract the exponents
-Find the power of the numerator and denominator and simplify
-Anything raised to the zero power equals one
-A negative power is a reciprocal
Terminating Decimals
Decimals that do stop .25
Repeating Decimals
When one digit, or a group of digits repeat endlessly 1.3333333...
Coefficient
A number that is multiplied by a variable in an expression or equation Ex 3x- 3 is quotient
Constant
A number whose value never changes 2x+5
Distributive Property
Multiply a sum by multiplying each addend separately and then add the products. 3(2+5)= 21
Like Terms
All parts of the expression except the coefficients are the same 2x +3x = 5x
Linear Inequality
An inequality that involves a linear function. Shading
Pythagorean Theorem
a (squared) + b (squared) = c (squared)
Domain
All inputs, x-values, term numbers
Range
All outputs, y- values
Vertical Line Test
Test in which if any vertical line crosses a graph at 2 or more points, then the graph doesn't represent a function
Nonlinear
Doesn't form a straight line
Function
A relation in which every input has exactly one output
Linear Equation
An equation in which every variable is raised to the first power Ex. y=mx+b
y-intercept
A point at which a graph crosses the y-axis
x-intercept
A point at which a graph crosses the x-axis
Scatter Plots
A graph in which the values at 2 variables are plotted along 2 axes
Parallel Lines
When 2 lines that do not intersect
Perpendicular Lines
2 lines that intersect at right angles 90 degrees
Rate Of Change
When one quantity changes when another related quantity increases by a unit amount, slope change in y over change in x.
Slope
Rate of change, rise over run, Y2-Y1 over X2-X1
Exponential Growth
F(x)=a*b "x" squared
a > 0 and b > 1
Exponents
A number used to indicate the number of times a term is being used to multiply itself.
Exponential Decay
A decrease in a quantity over a constant period of time. a>0 0<b<1
Exponential Function
A function whose exponent involves at least one variable. f(x)= a*b x squared+c
System of Equations
A group of two or more equations that involve two or more variables
3 types of Solutions of Systems of Equations
no solution 12=2
one solution(0,2)
infinate many solutions12=12
Systems of Inequalities
Two variables consists of at least two linear inequalities in the same variables (shading). 2 or more iniqualities.
Midpoint Formula
A formula used to find the middle of a line
NOW-NEXT statements
Recursive function. Next=now*5
Linear Regression
Line of best fit for a scatter plot
Bases
A number used as a repeated factor
