1. Quadratic Growth Modeling
Data AnalystBackground
An analyst has a set of data points representing the area of a square relative to its side length and needs to verify the mathematical relationship.
Problem
The analyst needs to find the exact quadratic equation and verify the fit for the sequence 0, 1, 4, 9, 16.
How to use
Enter the pairs 0,0; 1,1; 2,4; 3,9; 4,16 into the data field, set the degree to 2, and set decimal places to 2.
