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 based on its domain.

Front

How do you determine the range from a graph?

Back

To determine the range from a graph, identify the lowest and highest points on the y-axis that the graph reaches.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that are solved together.

Front

What does it mean to solve a system of equations?

Back

Solving a system of equations means finding the values of the variables that satisfy all equations in the system simultaneously.

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 a strict and non-strict inequality?

Back

A strict inequality (e.g., <, >) does not include the boundary value, while a non-strict inequality (e.g., ≤, ≥) includes the boundary value.

Front

How do you graph a system of inequalities?

Back

To graph a system of inequalities, graph each inequality on the same coordinate plane and identify the region where the solutions overlap.

Front

What is a solution to a system of equations?

Back

A solution to a system of equations is an ordered pair (x, y) that makes all equations in the system true.

Front

What does it mean if a system of equations has no solution?

Back

If a system of equations has no solution, it means that the lines represented by the equations are parallel and never intersect.

Front

What does it mean if a system of equations has infinite solutions?

Back

If a system of equations has infinite solutions, it means that the equations represent the same line, and every point on that line is a solution.
