(a) Plot the data by letting t be the years since 1990. Would a
linear or quadratic function model these data best?
(b) Find the quadratic function defined by f(t) =
a(t – h)? + k that models the data. Use the highest point
as the vertex, (h, k). Then choose (10, 986) as a second
point to determine a.
One of the two tables below shows data that can best be modeled by a linear function, and the other shows data that can best be modeled by a quadratic function. Identify which table shows the linear data and which table shows the quadratic data, and find a formula for each model.
