Use the graphing calculator to calculate the quadratic regression equation of the following data:

Question

Use your calculator to determine when y=4.2

Question 2 options:

-4.19

-3.99

4.19

3.99

Answer 1

Unfortunately, without the specific data points provided, I am unable to calculate the quadratic regression equation or the point where y=4.2. To find the solution to when y=4.2, you would need to input the data points into the graphing calculator and perform a quadratic regression. Afterwards, you would substitute y=4.2 into the equation and solve for x.
