Solving Inequalities with the Nspire

What is the primary reason for using graph relations over the 'in solve' method?

• Graph relations can solve equations that 'in solve' cannot

• Graph relations provide more accurate results

• Graph relations are faster

• Graph relations require less computational power

How do you access the less than symbol on a graphing calculator?

• Select it from the menu

• Press the 'less than' key

• Type it directly

• Use the control plus equals shortcut

What does an open circle on a graph indicate?

• The graph is incorrectly plotted

• The value is not included in the solution

• The equation is unsolvable

• The value is included in the solution

In graphing, what does shading to the left signify?

• No solution exists

• x is equal to a number

• x is greater than a number

• x is less than a number

What should you check if the graph does not display a dotted line as expected?

• If the equal to bar was initially present

• If the graph settings are correct

• If the inequality symbol is correct

• If there is an error in calculation

What does a filled circle in a graph represent?

• The value is included in the solution

• The graph is incomplete

• The equation has multiple solutions

• The value is not included in the solution

What does shading to the right on a graph indicate?

• The graph is incorrectly plotted

• x is less than a number

• x is equal to a number

• x is greater than a number

Why is it important to understand the direction of the shaded region in graphing inequalities?

• To use the graphing calculator effectively

• To calculate the exact values

• To choose the right type of graph

• To determine the correct inequality symbol

What does the presence of an 'equal to bar' in the graph indicate?

• The related value is included in the solution

• The inequality symbol is reversible

• The related value is not included in the solution

• The graph is plotted incorrectly

How do you input a fraction in the graphing calculator?

• Use the fraction key

• It cannot handle fractions

• Use the control divide shortcut

• Type the numerator and denominator separately
