Which equation represents the graphed function?
(0,-2) (4,-1)

Conclusion:

Working backward will create an equation, but remember that there are other equations that will also have that same set of solutions.

(Compare the solutions in 1a with 1b, and take a look at the graph at the right.)

Any equation of the form k(x2 + x - 12) = 0, where k is a constant, has the same solutions as  x2 + x - 12 = 0.
