New Flashcard 2.1, Inequality Graphs

Front

What does the inequality x ≤ 2 represent on a graph?

Back

It represents all values of x that are less than or equal to 2, including the point at 2.

Front

What does the inequality x < 3 represent on a graph?

Back

It represents all values of x that are less than 3, not including the point at 3.

Front

What does the inequality x ≥ 2 represent on a graph?

Back

It represents all values of x that are greater than or equal to 2, including the point at 2.

Front

What does the inequality x ≤ 4 represent on a graph?

Back

It represents all values of x that are less than or equal to 4, including the point at 4.

Front

What does the inequality x > 1 represent on a graph?

Back

It represents all values of x that are greater than 1, not including the point at 1.

Front

What is the difference between x < 3 and x ≤ 3?

Back

x < 3 does not include 3, while x ≤ 3 includes 3.

Front

How do you graph the inequality x < 4?

Back

Draw a number line, place an open circle at 4, and shade to the left.

Front

How do you graph the inequality x ≥ 1?

Back

Draw a number line, place a closed circle at 1, and shade to the right.

Front

What does an open circle on a graph indicate?

Back

An open circle indicates that the number is not included in the solution set.

Front

What does a closed circle on a graph indicate?

Back

A closed circle indicates that the number is included in the solution set.
