Question 1

Consider the second-order model

= -3.24 + 1.12x1 + 2.57x2 - 3.22x1x2 + 5.78 = 4.69

If x2 is held fixed at x2 = 3, describe the relationship between and x1.
◦ The relationship between and x1 is linear with positive slope.
◦ The relationship between and x1 is quadratic with upward concavity.
◦ The relationship between and x1 is linear with negative slope.
◦ The relationship between and x1 is quadratic with downward concavity.

Question 2
