X1 = number of machines to be repaired (NUMBER)

X2 = years of experience of service person (EXPER)

y = time taken (in minutes) to provide service (TIME)

Develop a polynomial regression model to predict average time on the service calls using EXPER and NUMBER as explanatory variables. Justify your model choice including transformations of any variables.
