Suppose we fit a curve with basis functions b1(X) = I(0 X 2) (X 1)I(1 X 2), b2(X) = (X 3)I(3 X 4)+I(4 < X 5). We fit the linear regression model Y = 0 + 1b1(X) + 2b2(X) + , and obtain coefficient estimates 0 = 1, 1 = 1, 2 = 3. Sketch the estimated curve between X = 2 and X = 6. Note the intercepts, slopes, and other relevant information
