12-74.

Find the equation of a cubic function that has as its parent graph, a locator point at

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,

*a*

and write the equation of the function.
