Functions
A relation in which each input value (independent variable) is associated with exactly one output value (dependent variable).
What is a function?
A ratio of two values, numbers, or expressions.
What is a fraction?
A square with each side one (1) unit in length.
What is a unit square?
A number or expression that is added to another number or expression. Example: In the equation 2 + 7 = 9, 2 and 7 are called this.
What is an addend?
A letter or symbol that represents a missing or unknown value. Generally the letter is lowercase and can be italicized.
What is a variable?
The variable in a function that is used to determine the value of a relation. When the relation is written as a set of ordered pairs, the x-coordinate is this. The set of values that can be used to replace this is named the "domain" of the relation.
What is an independent variable?
The dividend in a ration or fraction; The number that is above the fraction bar.
What is the numerator?
The measure, in square units, of the interior of a plane figure. Units such as square feet and square centimeters are used to measure this. The formula is length x width.
What is area?
The result when adding two or more numbers; the answer to an addition computation.
What is a sum?
A number or variable, the power of a number or variable, or the sum, difference, product, or quotient of a combination of numbers, variables, and/or powers of a number or variable. Examples: 3a, 15xy, 23b^2, etc.
What is an expression?
The variable in a relation that represents a value determined by the input. When a relation is written as a set of ordered pairs, the y-coordinate is this.
What is a dependent variable?
The divisor in a ration or fraction; the number that is below the fraction bar.
What is the denominator?
The distance around a closed 2-dimensional figure or shape. In the case of a circle, the distance around is the circumference.
What is perimeter?
The two or more numbers or expressions that are multiplied together; a whole number that can divide another whole number with no remainder.
What is a factor?
A mathematical expression that does NOT contain a variable.
What is a numerical expression?
In the relation y = 3x - 8, when the independent variable (x) is replaced by the number 5, the value of the dependent variable (y) is.......?
What is seven (7)?
Change 12 1/5 to an improper fraction.
What is 61/5?
The amount of space (in cubic units) that a three-dimensional (solid) figure occupies or contains. Units such as cubic meters, cubic inches, gallons, liters, and fluid ounces are used to measure this. The formula is length x width x height.
What is volume?
The result when one number or expression is multiplied by one or more numbers; the answer to a multiplication equation.
What is a product?
A mathematical expression that contains one or more variables.
What is an algebraic expression?
In the relation/function y = 2(x - 10), when the independent variable (x) is replaced by the number 20, the value of the dependent variable (y) is........?
What is twenty (20)?
Change 123/10 to a mixed number.
What is 12 3/10?
The sum of the areas of all the faces (sides) of a three-dimensional (solid) figure or object.
What is surface area?
The result when one number is divided by another number; the answer to a division computation.
What is a quotient?
A mathematical sentence or statement relating two equal expressions; may or may not contain variables. This always has an equal sign (=). Examples: 4 + 15 = 19 and w - 3 = 10.
What is an equation?
