Part 2

Interact with the app below by dragging the TWO LARGE POINTS. Then answer the questions that follow.

Suppose we graph the square root function [math]y=a\sqrt{x}+k[/math]. [br][br]What does the value [math]k[/math] do to the graph? Explain.

Suppose we graph the square root function [math]y=a\cdot\sqrt{x}+k[/math]. [br][br]What does the value [math]a[/math] do to the graph? Explain.

Check all the statements that are true for the square root function [math]y=a\cdot\sqrt{x}+k[/math].

When [math]k[/math] is negative, the graph always opens up (from left to right). When [math]a[/math] is positive, the graph always opens up (from left to right). When [math]a[/math] is negative, the graph always opens up (from left to right). When [math]k[/math] is positive, the graph always opens up (from left to right).

Check all the statements that are true for the square root function [math]y=a\cdot\sqrt{x}+k[/math].

When [math]k[/math] is positive, the graph always opens down (from left to right). When [math]a[/math] is positive, the graph always opens down (from left to right). When [math]a[/math] is negative, the graph always opens down (from left to right). When [math]k[/math] is negative, the graph always opens down (from left to right).

The graph of any square root function has an [b]endpoint. [/b][br][br]Check all the statements that are true for the square root function [math]y=a\cdot\sqrt{x}+k[/math].

When [math]k[/math] is positive, the graph has an endpoint above the xAxis. When [math]k[/math] is positive, the graph has an endpoint below the xAxis. When [math]k[/math] is negative, the graph has an endpoint above the xAxis. When [math]k[/math] is negative, the graph has an endpoint below the xAxis. When [math]a[/math] is positive, the graph has an endpoint above the xAxis. When [math]a[/math] is negative, the graph has an endpoint above the xAxis.
