Cubed Root

The number that multiplies itself 3 times in order to create a cubic value.

Absolute Value

Distance away from zero on the number line.

“6” is 6 away from zero,

and “−6” is also 6 away from zero.

So the absolute value of 6 is 6,

and the absolute value of −6 is also 6

*Distance is always positive

Coefficient

A number or symbol multiplied with a variable or an unknown quantity in an algebraic term.

Example: as 4 in the term 4x, or x in the term x(a + b).

Square Root

A value that can be multiplied by itself to give the original number.

Algebraic Expression

An expression of consists of one or more variables. It can contain some constants or some variables.

Dependent variable

A variable that depends on one or more other variables. For equations such as y = 3x – 2, the dependent variable is y. The value of y depends on the value chosen for x.

Independent variable

variable in an equation that may have its value freely chosen without considering values of any other variable. For equations such as y = 3x – 2, the independent variable is x.

Binomial

2 set of equations

Monomial

1 set of equation

Trinomial

3 set of equation

Polynomial

In mathematics, a polynomial is an expression consisting of variables (or indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. An example of a polynomial of a single indeterminate x is x2 − 4x + 7.

X intercept

the x-intercept is the point where the graph of the line crosses the x-axis.

Function notation

A function is represented by f (x) = 2x + 5. Find f (3). To find f (3), replace the x-

Relation

the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair ( x , y ) is in the relation. A function is a type of relation ..

Vertical line test

If a graph is a function or not. It’s has to pass the x and y axis

Zero of a function

Zero of a function means a function equal to the value zero.Find the f(x),x=3 and f(x)=x^2-9; f(3)=(3*3)-9 f(3)=0

Square root

4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root. Example: √36 = 6 (because 6 x 6 = 36)

Cube root

3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.

Radical

and many times it is used to determine the square root of a number. Radical. An expression that has a square root, cube root, etc. The symbol is √

Radicand

The number under the (radical) symbol. Example In √x, “x” is the radicand

Addition property on inequality

If the same number is added to both sides of an equation, the two sides remain equal

Division property of inequality

dividing both sides of an inequality by a negative number reverses the direction of the inequality.

Multiplication property of inequality

The two sides of an equation remain equal if they are multiplied by the same number.

Subtraction property of inequality

If the same number is subtracted from both sides of an equation, then the two sides remain equal.

Constant

That is, they’re the terms without variables example 4x+8

Commutative

When you swap numbers and get the same answer

Ex:Switch pairs 7+6=6+7

Associative

The associative property states that you can add or multiply regardless of how the numbers are grouped.

Inverse

undoes the action of the another function.

Identity

The variable keeps its identity A+0=A

Distributive

distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

Square Root

A value that can be multiplied by itself to give the original number.
