Identifying Math Properties in Equations

The additive identity property is shown in which of the following?

• 4 + (-4) = 0

• 1/4 x 4 = 1

• 0 + 1/4 = 1/4

• 4 x 1 = 4

Any nonzero number to the zero power equals ___________.

• one

• zero

• the base number

• two

On or around page 69, "Properties of Equality," the steps to solve an equation are justified by properties of equality. They ensure that the equations stays balanced in order to solve for the missing variable. Which of the following is NOT a property of equality?

• Addition Property of Equality

• Subtraction Property of Equality

• Zero Property of Equality

• Multiplication Property of Equality

• Distributive Property

Look at "Graph of Absolute Value Function" on or around page 110. The graph of an absolute value function has all of the following characteristics, EXCEPT which one?

• Its domain is all real numbers.

• Its range is all real numbers greater than or equal to zero.

• It has a vertical line of symmetry through the vertex.

• It has a horizontal line of symmetry through the vertex.

Refer to page 100, "Identifying Types of Functions." Linear functions have a common difference with a​ (a)   ​ rate of change. Exponential functions have a common ratio with a ​ ​ (b)   rate of change.

• constant
