b

Sketch a graph of the function.

c

A graph of $y=x^3$y=x3 is shown here. By dragging the points provided, plot the curve after it has undergone transformations resulting in the function $y=x^3-4$y=x34.

The graph of $y=x^3$y=x3 has been translated to the graph of $y=x^3+5$y=x3+5.

The graph of $y=x^3$y=x3 has been translated to the graph of $y=5+x^3$y=5+x3.
