1
Q

Cubed Root

A

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

2
Q

Absolute Value

A

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

3
Q

Coefficient

A

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).

4
Q

Square Root

A

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

5
Q

Algebraic Expression

A

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

6
Q

Dependent variable

A

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.

7
Q

Independent variable

A

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.

8
Q

Binomial

A

2 set of equations

9
Q

Monomial

A

1 set of equation

10
Q

Trinomial

A

3 set of equation

11
Q

Polynomial

A

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.

12
Q

X intercept

A

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

13
Q

Function notation

A

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

14
Q

Relation

A

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 ..

15
Q

Vertical line test

A

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

16
Q

Zero of a function

A

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

17
Q

Square root

A

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)

18
Q

Cube root

A

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

19
Q

A

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 √

20
Q

A

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

21
Q

A

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

22
Q

Division property of inequality

A

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

23
Q

Multiplication property of inequality

A

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

24
Q

Subtraction property of inequality

A

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

25
Q

Constant

A

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

26
Q

Commutative

A

When you swap numbers and get the same answer

Ex:Switch pairs 7+6=6+7

27
Q

Associative

A

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

28
Q

Inverse

A

undoes the action of the another function.

29
Q

Identity

A

The variable keeps its identity A+0=A

30
Q

Distributive

A

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

31
Q

Square Root

A

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