The table shows fuel consumption (in billions of gallons) by all non-military motor vehicles in selected years. What is the quadratic function that models the data? f(x) = (x-)² + (Round to three decimal places as needed.) C Let x = 0 correspond to 1970. Using (5,105.0) as the vertex and the data for 1990, find a quadratic function f(x) = a(x − h)² + k that models this data. Use the model to estimate fuel consumption in 1999.
