What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce. For example, if the range is -4 ≤ y ≤ 5, it means y can take any value from -4 to 5, inclusive.

Solve for n: -6n - 8 = 22

Back

n = -5

Front

Solve for u: u/4 = 8

Back

u = 32

What is the commutative property of addition?

Back

The commutative property states that changing the order of the numbers you are adding does not change the sum. For example, x + y = y + x.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept. For example, if the domain is -7 ≤ x < 5, it means x can take any value from -7 to just below 5.

Front

What is the associative property of addition?

Back

The associative property states that the way in which numbers are grouped when adding does not change the sum. For example, (a + b) + c = a + (b + c).

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other. For example, x < 5 means x is less than 5.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line. It can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

What is a variable in algebra?

Back

A variable is a symbol, usually a letter, that represents one or more numbers. For example, in the expression x + 2, x is a variable.
