What point on the line y = 3x + 8 is closest to the origin? Let D be the distance between the two points. What is the objective function in terms of the x-coordinate? I 2 D: 10x +48x+64 (Type an expression.) The interval of interest of the function is ( 00,09) . (Simplify your answer. Type your answer in interval notation.) The point on the line y = 3x + 8 closest to the origin is El. (Type an ordered pair. Simplify your answer. Type integers or simplied fractions.) Find the point P on the line y = x that is closest to the point (74,0). What is the least distance between P and (74,0)? C:) Let D be the distance between the two points. What is the objective function in terms of one number, x? D=D (Ti/De an expression.)
