Dynamic Visualization of Core Negative Power Function: Graphs and Mapping Diagrams
$f(x)=x^{-n} = \frac 1 {x^n}.$  $n >0$
• Notice the different scales for the axes on the mapping diagram.
• Move the slider to change the value of $n$.
• Check the box to see the table data visualized as arrows on the mapping diagram and points on the graph for the function.
• Select the point $x$ in the mapping diagram to move the point by mouse or use the scroll up or down key  to move by increments of 0.1.
