2. Using a response surface design, the tted second order model of the form 3'} = 20 10.131 + 10:1:2 + 102:3 22:? 73:3 53:3 + 4mm? axlmg 23:23:33 for the response 3; was obtained. a) Write down the matrix B for this model. b) Find the stationary point. c) Find the value gs of the predicted response at the stationary point. d) Find the eigenvalues of B. e) Write the model in the canonical form. What is the type of the stationary point? Can it be considered a ridge system
