How do you identify a quadratic function from a set of data points?

Back

A quadratic function can be identified by its parabolic shape when graphed. If the data points form a curve that opens upwards or downwards, it is likely quadratic.

How can you determine the best fitting quadratic model for a set of data?

Back

To determine the best fitting quadratic model, you can use methods such as least squares regression, which minimizes the sum of the squares of the residuals (the differences between observed and predicted values).

What is the difference between linear and exponential growth?

Back

Linear growth increases by a constant amount over equal intervals, while exponential growth increases by a constant percentage over equal intervals, leading to faster growth as time progresses.
