Column matrix
consisting of only 1 column
radical sign
composite of 2 functions
an operation that combines 2 or more functions (ie f(g(x)))
joint variation
z = k x y where k is the constant of variation
linear combination
also known as elimination or the adding of 2 linear equations
coefficient
the constant factor in a variable
direct variation
y = mx or y = kx
matrix
a rectangular array of numbers which are called elements
constant
a number
conjunction
a mathematical sentence formed using the word and
function
x values do not repeat, passes the vertical line test
domain of a function
all the x values possible for the function
fractional equation
a variable occurs in the denominator
inverse variation
y = k/x where k is the constant of variation
exponential equation
a variable appears as an exponent
discriminant
b^2 - 4ac of a quadratic equation and determines the nature of the roots
monomial
a constant, variable or product of a constant and 1 or more variables
completing the square
changing the form of a quadratic equation to make the left side a trinomial square
like radicals
have the same index number and radicand
median
middle number of data in numerical order
mode
number that occurs the most in a set of data
Quadratic formula
allows you to calculate the solution to any quadratic equation
factor a polynomial
the simplified product of other polynomials
Conjugate
where 2 binomials are identical except for the middle operation (ie. a + bi & a - bi) the product is a difference of squares
disjunction
a mathematical sentence formed using the word or
polynomial
a monomial or sum of monomials
quadratic equation in 1 variable
ax^2 + bx + c = 0
imaginary number
i = square root of -1
equation
mathematical sentence with an equal sign
Axes
x & y axis intersecting at the origin (0,0)
quadratic form
an equation that can be rewritten in the form A[f(x)]^2 + B[f(x)] + C = 0
LCM
the smallest positive monomial that all your terms will divide evenly into
prime factorization
writing a positive integer as a product of prime numbers
mean
average
Linear function
f(x) = mx + b
GCF
the largest expression that divides evenly into all of the terms
exponent
how many times the base occurs as a factor
empty set
no solution
extraneous solution
appears to be a solution but does not make the equation true
open sentence
a mathematical sentence that contains 1 or more variables
complex fraction
a fraction with numerator and/or denominator having 1 or more fractions or powers with negative exponents
quotient
the result of division
Standard form of linear equation
Ax + By = C
binomial
a polynomial with 2 terms
degree of a polynomial
the largest degree of its terms after its been simplified
Absolute value
the distance from 0 on the number line
complex number
where you have a real & imaginary part (a + bi)
Base of a power
the repeated factor of the power
cube root
the cube root of a number b is a solution to the equation or expression
parabola
a set of points equidistant from the line of symmetry and also has a vertex
