1-144.

Finite differences can be used to analyze the slope of a graph at various *x*-values. In Lesson 1.3.1, you found consistent patterns in the way polynomial functions change. Which polynomial function would have finite differences that grow by 4 each time?

*f*(*x*) is quadratic, for example, *f*(*x*) = 2*x*^{2}.
