Test 1 Final Review Algebra 1

Front

What is the range in inequality notation?

Back

The range in inequality notation represents the set of possible values for a variable. For example, 5 > y ≥ 1 means y can take any value between 1 and 5, including 1 but not 5.

Front

What is the domain of a function?

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) that will not cause any undefined situations, such as division by zero.

Front

How do you express the domain of a graph in interval notation?

Back

The domain of a graph in interval notation is expressed as a range of x-values. For example, -6 ≤ x ≤ 6 means x can take any value from -6 to 6, inclusive.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run). It indicates how much y changes for a unit change in x.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does '5 more than the product of 7 and s' mean in algebraic expression?

Back

It means the expression can be written as 7s + 5.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or equal to the other.

Front

What is the difference between domain and range?

Back

The domain is the set of all possible input values (x-values) for a function, while the range is the set of all possible output values (y-values) that result from those inputs.

Front

How do you represent a closed interval in interval notation?

Back

A closed interval is represented with square brackets, e.g., [a, b] means a ≤ x ≤ b.

Front

How do you represent an open interval in interval notation?

Back

An open interval is represented with parentheses, e.g., (a, b) means a < x < b.
