Quadratic Regression Standard Form and Tricky Translation

This video explains an SAT question that can be solved using Quadratic Regression in Standard Form and Translation in Desmos.

The table shows three values of x and their corresponding values of y, where y = f(x)+4 and f is a quadratic function. What is the y-coordinate of the y-intercept of the graph of y = f(x) in the xy-plane?
