Question 1

Cubed Root

Answer 1

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

Question 2

Absolute Value

Answer 2

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

Question 3

Coefficient

Answer 3

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).

Question 4

Square Root

Answer 4

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

Question 5

Algebraic Expression

Answer 5

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

Question 6

Dependent variable

Answer 6

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.

Question 7

Independent variable

Answer 7

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.

Question 8

Binomial

Answer 8

2 set of equations

Question 9

Monomial

Answer 9

1 set of equation

Question 10

Trinomial

Answer 10

3 set of equation

Question 11

Polynomial

Answer 11

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.

Question 12

X intercept

Answer 12

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

Question 13

Function notation

Answer 13

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

Question 14

Relation

Answer 14

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 ..

Question 15

Vertical line test

Answer 15

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

Question 16

Zero of a function

Answer 16

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

Question 17

Square root

Answer 17

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)

Question 18

Cube root

Answer 18

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

Question 19

Radical

Answer 19

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 √

Question 20

Radicand

Answer 20

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

Question 21

Addition property on inequality

Answer 21

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

Question 22

Division property of inequality

Answer 22

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

Question 23

Multiplication property of inequality

Answer 23

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

Question 24

Subtraction property of inequality

Answer 24

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

Question 25

Constant

Answer 25

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

Question 26

Commutative

Answer 26

When you swap numbers and get the same answer

Ex:Switch pairs 7+6=6+7

Question 27

Associative

Answer 27

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

Question 28

Inverse

Answer 28

undoes the action of the another function.

Question 29

Identity

Answer 29

The variable keeps its identity A+0=A

Question 30

Distributive

Answer 30

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

Question 31
