Find the equation of a cubic function that has as its parent graph, a locator point at , and passes through the origin. Homework Help ✎

Substitute the locator point (h, k) into the general equation

Use the known point, other than the locator point that lies on the graph, to solve
for the stretch factor, . In this case, you are given the origin, . Solve for a
and write the equation of the function.
