Front

What is the range of a graph?

Back

The range of a graph is the set of all possible output values (y-values) that the function can produce. For example, if a graph has a range of 0 ≤ y ≤ 2000, it means y can take any value from 0 to 2000.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution to the system is the point(s) where the equations intersect on a graph.

Front

How do you find the value of x in a system of equations?

Back

To find the value of x in a system of equations, you can use substitution or elimination methods to solve for x.

Front

What does the notation 0 ≤ y ≤ 2000 represent?

Back

This notation indicates that y can take any value from 0 to 2000, inclusive.

Front

Back

The solution is x = -2.

Front

What is the meaning of RANGE in a function?

Back

The RANGE of a function refers to the set of all possible output values (y-values) that the function can produce.

Front

What does the notation -2 ≤ y < 1 represent?

Back

This notation indicates that y can take any value from -2 to just below 1, including -2 but not including 1.

Front

How do you determine if a point is in the solution set of a system of inequalities?

Back

To determine if a point is in the solution set, substitute the point's coordinates into each inequality. If the point satisfies all inequalities, it is in the solution set.

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.

Front

What does the symbol ≤ mean?

Back

The symbol ≤ means 'less than or equal to.' It indicates that the value on the left can be less than or equal to the value on the right.
