Extracted text: Q1: A chemical process having two input variables and one output variable. If the response of the output variable Y(t) to a separate step change in the input variables X1 and X2 were recognized as presented in tables 1 and 2 respectively. Predict the parameters of the transfer function that relates the output variable as a function of input variables.
