Question: A behavioral researcher finds that the attention span $ A(t) $ (in minutes) of children during a tech-based activity after $ t $ hours is modeled by a quadratic $ A(t) = pt^2 + qt + r $. If $ A(1) = 25 $, $ A(2) = 32 $, and $ A(3) = 33 $, find the maximum attention span predicted by this model.
