In the given cubic equation form of
, both h and k cause the graph to be transformed from the parent function.
The variable h affects the graph by dictating the horizontal shift. If, for example, we have "x - 1," the graph will be shifted one unit to the right.
The variable k affects the graph by dictating the vertical shift. If, for example, we have "- 5," the graph will be shifted 5 units down.
