Short Answer
George measures the force exerted by a certain spring when it is stretched various distances beyond its natural length. The data he gathers is compiled in the following table.
- He wishes to describe the force as a function of the stretched distance, and decides to use a quadratic function model. After fitting a quadratic function to the data, he uses it to estimate the force when the spring is stretched 19 inches. What is his approximation (to three decimal places) of this force?
